I can't believe I watched a 15 minute video about an air filter. But it was very well done, and it convinced me to subscribe. I m still on the fence about buying an Interceptor but videos like this are warming me up to the idea that I could live with 45 horsepower.
@@stuartfillingham, honestly I'm really tempted because it looks so much like my first street legal bike, a 78 Honda CB550f. I even painted it almost that same burnt orange. Next summer it's either a new Royal Enfield or a used Honda CB1100ex. I'm getting old though, so the lighter R.E. is looking pretty good.
If you were my teacher at school... I would have paid more attention. Excellent explanation. I'm test riding one of these tomorrow... can't wait! Been riding 3 years, my current bike is a suzuki gsf 650, but when I saw my boss rock up to work in his new royal enfield, I knew I wanted one... and tomorrow, I may be a proud owner.
Stewart, as a result of watching this video, I bought a DNA air filter for my car a Kia Picanto 1.25cc to replace the stock airbox filter. I wasn't expecting any performance difference at all, I just liked the idea of the long life of the product. Now I know that you are an honest and sensible guy, so I trusted your opinion and I am so glad that I did!. The filter has made a very noticeable improvement to the torque and runs more freely, the engine is more relaxed and copes with any situation that I ask of it!. The fuel economy has improved, acceleration is quicker, it really does feel like the car has had a larger engine fitted!
Spend spend spend! Me too! Over the past 24 hours I have blown £70 on a luggage rack and £40 on a DNA filter for my classic 500. And it’s all Stu’s fault! I daren’t think about what I’m going to spend tomorrow. I might even get an Interceptor, after all, it’s only money 💸💸💸 PS: I might just go easy by following Stuart‘s recommendation by buying a NKG spark-plug. Oh, wait... 🤔
Another great video, on a product that seems Necessary! Amazing how manufacturers use budget parts on things that effect performance, a thing I noticed coming from the Harley world, a few quid at the manufacturing stage could add so much enjoyment for the owner. Another great common sence production. Keep up the great work.
Sir, I was just blown away by the incredible amount of information you provided here! This screams of a real passion for motorbike, not just shallow throwing things at it. Thanks so much! I plan to get Int 650 myself, in Bakers Express colors. Would you by any chance adding any leather or waxed cloth vintage travel bags? Couldnt find any online without the need of a massive metal rack. Triumph has some nice looking bags
Hi from Argentina! I installed the DNA filter and have the same sensations as you. But you expressed them with the proper words. Thanks for the recomendation of run the engine 12 minutes, to allow the electronics make the necessary changes.
Hola Marcelo, que es lo que dice? que hay que dejar el motor funcionando con el nuevo filtro 12' en ralentí? para una moto refrigerada por aire me parece mucho.
Excellent Video as always, Mr Fillingham.... Your video convinced me to go with DNA. I thought that I noticed a distinct new "growl" out of the engine after installing my new DNA air filter. Between the air filter and my new mufflers, I hear beautiful tones while riding my Interceptor on the beautiful roads of the Arkansas Ozarks......
Stuart, slightly off topic but there is a very interesting article in the weeks MCN regarding S&S performance parts for the Enfield 650. These include stainless steel exhaust cans and a 865cc big bore kit. Well worth a read.
S&S filter and plate ordered. No DNA I. The states I could find. Nope don't have 100 miles on this motorcycle yet. Going to change the filter at my first service. Looking so forward to it though!!! Love your videos!
Thanks uncle Stu for the great explanation about the inner workings of the air filter. I've been using the DNA air filters on my bikes for at least 5 years now and I have been happy with them.
regarding the Tip to Letting the Engine run at idle to its optimum operating temperature, some say you need to wait until the fan starts to operate. this applies to water-cooled motors, so your Triumph might need this if you ever do the same thing on it. I don't know if it is true or not but it seems many say to wait until the fan kicks in.
Hi Stuart. Hitchcock superb service ,ordered filter and mirror plugs yesterday ,today all fitted run for 13mins then few miles around the town ,sounds great. Job done next Thanks to your videos 👍
Much appreciated Stuart. In the states we have K&N filters available. Quite similar. Added a couple of lower restriction mufflers and the sounds are glorious indeed from my GT650. I very much appreciate your attention to the details and nuances of wrenching on these bikes while delivering your message in poetic fashion. Thanks very much.
Induction roar on my Kymco AK550 with DNA was enhanced further by fitting a small aluminium louvered cover to the lid above the still air box. This lid is between the riders knees and not hidden/ sound muffled by a petrol tank. A most enjoyable sound further enhance by the Arrow exhaust muffler and 270 degree firing sequence. Brings joy to this 68 year old.
Increase in torque is increase in power. Torque times revolutions equals power. One should maybe claim that not the >maximum< power is more, but the power over the mostly used rev band.
I have just installed the DNA filter on my Classic 350 (2022) and the performance is absolutely better. Sure it did not turn into a race bike but the ride is a delight even more so than before. I recommend it 100%. One note though: at least from my experience, the 12 minute idle run after installation did not do anything. On The first ride after installation, performance did not feel better and actually felt a bit worse than before, which was disappointing. I thought that’s the end of it. However, during my rides on the following days the engine felt better and better, like it’s “learning” during actual rides rather than running on idle.
Touring the USA on my Royal Enfield Interceptor 650, putting in a lot of miles per week it seemed like my life revolved around always cleaning, lubing, and adjusting the chain, trying to keep close the manufacturers recommend intervals 1,000km/621mi, which I can easily do in a day. I really wanted to keep My Royal Enfield stock but eventually broke down and installed the Bandidos Pitstop Belt Drive conversion kit. I love it! Even being very picky to clean off excess lube, after 17,000mi/27,000km it took forever to get it cleaned off all the little cracks and crevices. Plus it is smoother and quieter which I wasn't expecting. The downfall for my use is the gear ratio they use between the front and rear pulleys give more torque, which I don't care about while touring. That also means my gas mileage has gone down. I'm still using the stock paper filters. You mentioned in this video you would be checking for fuel consumption increase later. Did you check? What was the result? What video is it on? Thank you so much for your quality videos!
Hi Mr. Straut, great content and much relevant to us normal riders. I have seen a lot of pistons getting fried because the engine was running lean. Please let us know your comments on long term effect of performance air filters. does learning ecu helps in solving this issue of running lean??
Usually, you would want to get a tune right away since now allowing more flow thru the air filter you have now kind of changed the air fuel mix ratio. But like you said the ecu will make adjustments but idk how true that is tho.
Love your vids , am 74 and worked my years in the industry , meaning incredible long rides for vacations on many different bikes , started on the first hondas than came to Canada a cub trail 50cc and ended with a Ducati my riding love affair . The desmodronic sound gave me biking orgasm
Sigh. Every time I come up with some question about how to make my INT 650 better, you have already elegantly, comprehensively, and satisfactorily answered it. Save some for the other TH-camrs Mr. Fillingham! Thanks so much for your great videos.
A rather splendid video descriptive my sir. It’s indescribable, the feeling of passing molecules onto the combustion chamber. Why would anyone someone suffocate such a power house
I have been reading these posts with interest because of a recent purchase of a DNA filter, this was purchased purely for the fact that it does not need to be replaced (only re-oiled). When I fitted the new filter I went through the 15 minute idle routine as mentioned in several posts and other bloggers, took the bike for a ride and the engine seemed to be struggling to accelerate smoothly especially from low revs and vibration. The next day the same result, the engine was definately down on performance in many ways and not pleasant to ride. I don't know anything about "self learning ECU's" or performance plugs but I do know that my ECU did not want to know about an increase in air flow from the new filter. As a possible solution to the self inflicted "problem" (the bike was working fine before the filter replacement) I replaced the original snorkel covering the air filter and went for a ride. Immediately the bike was buzzing along beautifully, smooth acceleration from any revs, the vibration problem disappeared and the world was wonderful again. So I'm happy with the result, a reusable air filter and a bike that puts a smile on my face when I ride it, life is good.
Hey Stuart, what’s your take on using this type of free flow filter with stock exhaust? I am not looking for any major power upgrade but always liked the idea of things being more smoother. Will the engine be affected in anyway if I use this with stock exhaust?
Totally agree, fitted the DNA filter to my XT660Z Tenere and the best improvement is the 'characteristic' change..more important than HP figures. You are aware the engine is breathing better. A DNA filter and free flowing exhaust will make a big difference to the 'way' a bike rides. Cheers, Steve
Hi Stuart, I love your very informative and exhaustive videos 👍🏻. I need a clarification though. Isn’t the stage 2 kit meant to be used with free flow cans? Or can we use the DNA air filter along with the stage 2 kit with the stock exhausts without any heating or engine issues.
Great video Stuart, I hope they do the filter for the Himalayan 👍🏻, and you have an uncanny knack of making my bank account have less and less in it, every time you review something 🤣👍🏻
@Mark Dolby - HAHA! I too keep going shopping after his videos - first it was the Tank Knee Pads, then the Tank SS bag frame both from Motone Custom, Oxford heated hand grips - although I don't think he has discussed those or fitted them, and now the air filter and cover plate!
Excellent video This is an upgrade that I'd decided to do on my Interceptor when I first found out about this product. I had a very similar setup on one of the bikes I had way back in the day and to be totally honest I didn't fit the filter just for a little bit of extra performance, because the bike didn't need it, I fitted the filter for that gorgeous sounding induction roar. I'm going to fully run my bike in before I change the filter because I want to be able to see what difference it makes.
Great video, really enjoyed your detailed commentary. So right about leaving the ECU to 'learn' too. I did the same mod a few years ago on a KTM Duke 390, with a K&N filter & my findings mirror yours.
My only concern would be water. I usually daily motorcycles, which means leaving them at my office all day while raining, riding in the rain... Have you noticed any water entry?
ok that does it! I'm not touching my bike until I check in with Stuart first. Thanks Stuart for explaining what I did incorrectly. I purchased the DNA filter a month ago not because I wanted more power but because I used to race off-road and I know the benefit of a high performance air filter for power consistency but also because it's cheaper in the long run to clean your filter instead of replacing it. But, my bikes never had fuel injection and an ECU so I replaced my stock filter with the DNA and rode the bike like I normally do to work. My INT is a commute bike and so it rode fine to work, but later in the day when I started it to go home, it wouldn't idle and it was very rough idling when I got it to start. I had to be careful on the way home to not let the revs drop below 3k or it would stall. When I got home I thought I must have done something wrong so I removed the filter and put back in the stock filter and left it that way for about a week. I then thought that was crazy as this must be working for others so I decided to trouble shoot it. I put it back in and started the bike and I must have gotten dumb lucky as I let it idle while I looked around. Of course there was nothing I could do so I didn't change anything but after a few minutes it seemed to be idling just fine. So I then took it out and rode it and stopped it and let it sit, and started it and rode it and everything seemed to be working properly. I then went back to commuting with the DNA installed and it's been great since. I agree that there really isn't anything noticeably different, but I wasn't expecting anything as my reason to install it is for better long term consistency and for a less costly maintenance. Thanks for the great write-up again!
Had heard 2016 on bonneville had self learning ecu, did not know it was widespread, I bought a second hand 2015 bonneville with lambda removed dna filter and breathe filter, standard exhaust. It runs out of puff at 20mph below listed top speed. Not knowing what tune it has had done I am guessing it has not and is running lean so bought new snorkel to revert to standard, tunes available are for free flowing exhausts anyway. Incidentally I was going to buy an interceptor until I saw your post about bad threads, nearly bought new Scrambler then settled for 2015 efi bonneville
Perfect timing, it’s an upgrade I’m planning to carry out. So it’s good to see a review beforehand. Great info regarding the ecu. Haven’t seen that mentioned anywhere else, so thanks for that. Cheers, Martin.
I think many people are just ignorant of it Martin, as with the LC Bonnevilles when they were first introduced. The ECU will cope eventually if you dont do it, but this way ensures a glitch free install.
It can be hard to quantify the change on a fuel injected engine, but way back when... I added 4 K&N filters to my 1980 KZ650. This required a re-jet of the carbs. I can't remember for sure what size they were due to 40 years, but I am thinking that I had to go from a 120 to a 125 main jet in each carb and raise each needle valve by 1 notch to get enough fuel to keep it from running lean. More air + more fuel = more power. It probably was no more than 3 hp, but it could be felt in the seat of the pants. Will the Interceptor's fuel injection give that much adjustment without a remapping? Probably, but only Royal Enfield can say for sure. As long as it is running smoothly, it should be OK. If it is lean, you can feel it as an uneveness, sort of like not being able to hold the throttle steady. It won't be nearly as pronounced as a misfire, but more subtle.
No all fuel injection is controlled by the ECU and all vehicle ECUs must be self learning now to adapt for any configuration changes. although granted a remap may produce a little more performance.
hello, on my continental gt 650 i installed a dna filter and replaced the silencers. my mechanic thinks that I have depleted the fuel supply and recommends that I put on a dynojet or a powertronic. What do you think ? Thanks for you great video
I think hes trying to make some extra cash out of you. The bike has a learning ECU so it will adjust for the changes you have made. They are designed to run lean to meet emissions laws.
In the race cars I moved on from a oiled cotton gauze air filter for my racing engines some years ago. However the interceptor presents a conundrum at the moment. It appears that the style of air filter that I prefer for my high performance Chevrolet motors doesn’t seem to exist yet. Maybe I should start selling them myself. R2C type filters are what I prefer for high RPM, dirty environment action. If you’re not familiar with the racing which I am talking about, I have some videos on my channel.
@@stuartfillingham Just ordered the kit ....I have a black magic Conti GT....i am still concerned with the stupendousssss amount of dirt we have here in India .....fingers crossed
I was lucky I got a 2022 interceptor the other day With DNA filter fitted 16t sprocket, GT tank and bar risers fitted, like brand new with just over 1k miles on it, I won’t say hoe much it cost me but it was by far the best bargain I’ve ever purchased, I’m still in shock and absolutely love it,
Hi Stuart, does Interceptor 650 have a learning ECU ?I reckon they are old school, the lookup tables sort ! The entries in the lookup tables doesn’t just change like that ! Or does it ? Please throw some light !! Have you tested it on a dyno after adapting the DNA filter ? Any interesting numbers ? Your fan from India 🇮🇳 Cheers !!
Lets say a person was going to install this filter system, but also install S&S mufflers and high flow header pipes. Would you recommend making all of the mods at once and then updating the ECU or updating the ECU after each individual mod so that the ECU does not have to make one large adjustment, but instead several small adjustments? As always your videos are very informative and easily understood. Thanks!
The air filter is important however I can't help but wonder what changes to the flywheel would do . The Enfield appears to be one of those bikes that responds to fettling. Bikes like this are rewarding to own . Keep the vids coming.
Great video, but I'm a bit concerned about installing the DNA filter without the stock snorkel. Isn't there a risk of drawing water in there when it rains?
Since you ride in a country where it rains even more than in Belgium, I'll trust your expertise on that😉 as for washing I follow the "full fillingham", so no worries there😁
Changing the stock air filter to the DNA Kit was the very first modification I did. The engine felt more powerful and responsive. Maybe also due to a noticeable increase in volume when fully opennig the throttle at medium revs. The induction noise might fool us, as our ears tend to make us feel that louder is quicker. Thank you for the information about the self learning process of the ECU. I'll go downstairs now an give the bike an idle run.
Ime in AUS, so different regulations, but in England what will fitting one of these do to your engine warranty.? I am tipping if there’s an issue the Enfield dealer will take the chance to dodge warranty claims if you fit a non Gen part ?
Hi Stuart very informative video's, thanks for your effort. could you do a video on cleaning the filter as most of the ones I have watched on TH-cam show cleaning the outside and these on the interceptor draw the air in from the inside. Tim
I would have never thought be so interested by an air filter présentation... Thanks sir, interesting and informative, as usual ! Hi from Paris.
Thanks. This is a no-bullshit channel. No hype. Very helpful. Unique and pleasant accent. Keep it going, I will buy an Interceptor very soon.

I had a very similar setup on one of the bikes I had way back in the day and to be totally honest I didn't fit the filter just for a little bit of extra performance, because the bike didn't need it, I fitted the filter for that gorgeous sounding induction roar.
I'm going to fully run my bike in before I change the filter because I want to be able to see what difference it makes.
I'm assuming the same would be true for the 350 meteor as well ?
First class video Stuart, informative and interesting and beautifully shot too, i never thought an air filter could be made to look sexy lol
I always enjoy your videos. Very informative
Great video, really enjoyed your detailed commentary. So right about leaving the ECU to 'learn' too. I did the same mod a few years ago on a KTM Duke 390, with a K&N filter & my findings mirror yours.
definitely going to have a go at that mod. Cheers Stuart. Always excellent information.
Such an elaborate explanation!!! Excellent.
Thanks again, Stuart. You've answered my question about the difference between S&S and DNA filters - they are the same! :)
My only concern would be water. I usually daily motorcycles, which means leaving them at my office all day while raining, riding in the rain... Have you noticed any water entry?
Would like to know it as well
Great explanation! I just ordered my kit for my brand new black interceptor 650.
What do you think of the air box delete kits? I've been told pod filters let dirt into the engine. Plus I think they are illegal in Australia
A Shakespearean delivery of an otherwise mundane subject. Thanks!
ok that does it! I'm not touching my bike until I check in with Stuart first. Thanks Stuart for explaining what I did incorrectly. I purchased the DNA filter a month ago not because I wanted more power but because I used to race off-road and I know the benefit of a high performance air filter for power consistency but also because it's cheaper in the long run to clean your filter instead of replacing it. But, my bikes never had fuel injection and an ECU so I replaced my stock filter with the DNA and rode the bike like I normally do to work. My INT is a commute bike and so it rode fine to work, but later in the day when I started it to go home, it wouldn't idle and it was very rough idling when I got it to start. I had to be careful on the way home to not let the revs drop below 3k or it would stall. When I got home I thought I must have done something wrong so I removed the filter and put back in the stock filter and left it that way for about a week. I then thought that was crazy as this must be working for others so I decided to trouble shoot it. I put it back in and started the bike and I must have gotten dumb lucky as I let it idle while I looked around. Of course there was nothing I could do so I didn't change anything but after a few minutes it seemed to be idling just fine. So I then took it out and rode it and stopped it and let it sit, and started it and rode it and everything seemed to be working properly. I then went back to commuting with the DNA installed and it's been great since. I agree that there really isn't anything noticeably different, but I wasn't expecting anything as my reason to install it is for better long term consistency and for a less costly maintenance. Thanks for the great write-up again!
Ah I guess you were just unlucky scott people do often get away with it but the ECU will occasionally just get confused and get stuck! no harm done!
Can you add a performance air filter to your INT/GT 650 with a stock muffler/silencer?
Yes, makes a small difference to the bottom and midrange but improves the sound as well.
Thank you very much, Stuart! You are truly the treasure trove of information! ATB🙏🏻🍀
Hello stuart fillingham, have you had an opportunity to investigate the Airbox removal kit for Royal Enfield Interceptor / Continental GT 650 by BAAK?
This is one of the first Mods that I did.....
Hi. Great video. Can you talk about the seat perhaps?
in due course!
Had heard 2016 on bonneville had self learning ecu, did not know it was widespread, I bought a second hand 2015 bonneville with lambda removed dna filter and breathe filter, standard exhaust. It runs out of puff at 20mph below listed top speed. Not knowing what tune it has had done I am guessing it has not and is running lean so bought new snorkel to revert to standard, tunes available are for free flowing exhausts anyway. Incidentally I was going to buy an interceptor until I saw your post about bad threads, nearly bought new Scrambler then settled for 2015 efi bonneville
Perfect timing, it’s an upgrade I’m planning to carry out. So it’s good to see a review beforehand. Great info regarding the ecu. Haven’t seen that mentioned anywhere else, so thanks for that.
Cheers, Martin.
I think many people are just ignorant of it Martin, as with the LC Bonnevilles when they were first introduced. The ECU will cope eventually if you dont do it, but this way ensures a glitch free install.
It can be hard to quantify the change on a fuel injected engine, but way back when... I added 4 K&N filters to my 1980 KZ650. This required a re-jet of the carbs. I can't remember for sure what size they were due to 40 years, but I am thinking that I had to go from a 120 to a 125 main jet in each carb and raise each needle valve by 1 notch to get enough fuel to keep it from running lean. More air + more fuel = more power. It probably was no more than 3 hp, but it could be felt in the seat of the pants.
Will the Interceptor's fuel injection give that much adjustment without a remapping? Probably, but only Royal Enfield can say for sure. As long as it is running smoothly, it should be OK. If it is lean, you can feel it as an uneveness, sort of like not being able to hold the throttle steady. It won't be nearly as pronounced as a misfire, but more subtle.
No all fuel injection is controlled by the ECU and all vehicle ECUs must be self learning now to adapt for any configuration changes. although granted a remap may produce a little more performance.
@@stuartfillingham That's good to know.
Any update on the effect on fuel efficiency ??
hello, on my continental gt 650 i installed a dna filter and replaced the silencers. my mechanic thinks that I have depleted the fuel supply and recommends that I put on a dynojet or a powertronic. What do you think ?
Thanks for you great video
I think hes trying to make some extra cash out of you. The bike has a learning ECU so it will adjust for the changes you have made. They are designed to run lean to meet emissions laws.
In the race cars I moved on from a oiled cotton gauze air filter for my racing engines some years ago. However the interceptor presents a conundrum at the moment. It appears that the style of air filter that I prefer for my high performance Chevrolet motors doesn’t seem to exist yet. Maybe I should start selling them myself. R2C type filters are what I prefer for high RPM, dirty environment action. If you’re not familiar with the racing which I am talking about, I have some videos on my channel.
Thanks for the information Stuart, I can only see 360p as the resolution option ....just wanted to let you know....don't know if its just me.
Hi Abhishek yes that quite normal in the first couple of hours of upload. You Tube will take some time to process the video to full resolution.
@@stuartfillingham Just ordered the kit ....I have a black magic Conti GT....i am still concerned with the stupendousssss amount of dirt we have here in India .....fingers crossed
I was lucky I got a 2022 interceptor the other day
With DNA filter fitted
16t sprocket,
GT tank and bar risers fitted, like brand new with just over 1k miles on it, I won’t say hoe much it cost me but it was by far the best bargain I’ve ever purchased, I’m still in shock and absolutely love it,
Im using performance dry air filter, it causing my bike over heating.iam using it with stock exhaust
With this "upgrade" does any harm when it rains??
Thanks for explaining sir. Just a question; what is that on the left side just before the mirror? On the left handle while you’re riding?
Another spot on, very good and instructive video Stuart.
Hi Stuart, does Interceptor 650 have a learning ECU ?I reckon they are old school, the lookup tables sort ! The entries in the lookup tables doesn’t just change like that ! Or does it ? Please throw some light !!
Have you tested it on a dyno after adapting the DNA filter ? Any interesting numbers ?
Your fan from India 🇮🇳 Cheers !!
Al bikes sold in EU, common wealth and USA must have learning ECUs by law since 2015!
Lets say a person was going to install this filter system, but also install S&S mufflers and high flow header pipes. Would you recommend making all of the mods at once and then updating the ECU or updating the ECU after each individual mod so that the ECU does not have to make one large adjustment, but instead several small adjustments? As always your videos are very informative and easily understood. Thanks!
The air filter is important however I can't help but wonder what changes to the flywheel would do .
The Enfield appears to be one of those bikes that responds to fettling.
Bikes like this are rewarding to own .
Keep the vids coming.
Great video, but I'm a bit concerned about installing the DNA filter without the stock snorkel. Isn't there a risk of drawing water in there when it rains?
Not really jan, just watch what your doing with the hose when washing the bike!
Since you ride in a country where it rains even more than in Belgium, I'll trust your expertise on that😉 as for washing I follow the "full fillingham", so no worries there😁
Changing the stock air filter to the DNA Kit was the very first modification I did. The engine felt more powerful and responsive. Maybe also due to a noticeable increase in volume when fully opennig the throttle at medium revs. The induction noise might fool us, as our ears tend to make us feel that louder is quicker. Thank you for the information about the self learning process of the ECU. I'll go downstairs now an give the bike an idle run.
no need if you've been running it for a while. they do sort themselves out eventually.
Ime in AUS, so different regulations, but in England what will fitting one of these do to your engine warranty.? I am tipping if there’s an issue the Enfield dealer will take the chance to dodge warranty claims if you fit a non Gen part ?
Was waiting for it. 👍
Hi Stuart just a small question,, do we need to have a free flow exhaust for stage 2 fitting .
Hi Stuart very informative video's, thanks for your effort. could you do a video on cleaning the filter as most of the ones I have watched on TH-cam show cleaning the outside and these on the interceptor draw the air in from the inside. Tim
I noticed you were going to fast around those twistes and it was wet ride safe
Police trained rider Anthony, was well within my capabilities but thank you for your concern.
