0:45 "The power curve is really wavy, it shouldn't look like that on a 911. It should be much smoother"
3:00 "These engines always have a wavy line, I'm not concerned"
Damn Charlie, make up your mind son!
What’s the real answer lol
He said at the top. Wavy lines at the top are common, but not in the middle.
You just hear what you want to. Open your ears.
This is why I don't go to "mechanics" with a dyno. Kudos Gazza as I came to write the same comment basically. The hypocrisy is unreal. Let me do a translation:
"Oh so you've cleaned the injectors, replaced the cats, and exhausted all the options I was planning on fixing this wavy graph. In that case these engines are meant to be wavy like that"
When I watched this I thought, "This is the very definition of BULLSHIT!!" Making shit up as you go...
Your 996 deserves a new stainless steel exhaust system ;)
and some sexy wheels
and a new IMS. I'm amazed he has not changed it. Should have been done first thing after purchasing
Not the conventional thinking in the UK...it's a US thing.
Errr first thing I had done to my 996 from a specialist in Leeds £1099+VAT peace of mind priceless.
Which bearing?
I love the way the electric boot spoiler went up because the car thought it was going fast on a road😂
And why wouldn't it !
It was doing 70+mph according to the wheel speed so it should come as no surprise.
Kristian Larsen I felt bad for the car, because it was being pranked by its owner.
@@LordPrometheous It's like object-permanence tests on puppies. Kinda makes you cry a bit.
Rather strange comment... :/ Of course it does...
We need more of this instead of car reviews... Even though they are also great!
Don’t forget aftermarket filters don’t filter as well ( 75% vs 99% for original ) as original filters and can screw your maf if over oiled.
When you first put the bmw on dyno at 6:00 I was noticing how steady it was and just then you said that a nice smooth curve I was noticing how steady the car was on the machine itself. Seemed real smooth. Nice video thanks for posting. And yes it seems these usually give some slight power increase but mostly people keep them on because like them I like the sound better.
I do like the way you approach these videos with the enthusiasm and enough naievety to ask the questions that most of us want to ask. Keep up the good work.
The panel filter should always be seen as a supporting mod when pushing on further. Probably see benefits post exhaust and remap.
Wow very nice technical configuration video
I drive an f56 mini cooper s which with the oem filter actually hit 208bhp & after fitting a k&n panel filter dropped to 198 bhp but with such a negligible drop the increased noise ,especially windows up believe it or not was well worth it &im convinced the throttle response is improved and there really does seem to be more popping on the over-run! I have an induction kit en rout & am really really interested to get it dynod again &really try put this to bed once & for all, awesome content. Cheers
Like that Matt does real world tests and nice to see you review older cars. Fantastic video!
I installed the K&N filters in my Macan S, which require powerwashing and oiling yearly, but I too didn't really see a big upgrade. The COBB tuner, which remapped the ECU, did make a big difference on the high end, put not so much on the low end where I wanted to see gains. It also eliminated the exhaust sound, which as you say, is really a big part of owning a Porsche ! I reset me car back to factory settings, and returned the tuner, but the filters remain. Thanks, well done video !!
i really do love project/ wip videos like these.
Brilliant video. That’s the sort of stuff we wanna see Matt.👍🏻
These filters work on some cars I fitted a K&N in box filter on my 309gti and I noticed 3 benefits nice induction roar 2nd definate increase in power and it actually filtered the air with the old filter there was always dust in the intake track.
In addition your aftermarket filter is (should be) serviceable where paper elements aren’t, they’re throw away item which cost you every time a services due. If you replacement paper filters aren’t that expensive then whatever you like but it’s it’s a high cost item then a good quality serviceable aftermarket filter is worth a look.
Great video you guys should definitely do some more like this
Great video/vlog. Please make many of those.
Matt, what about a BMW E60 M5 you said you would like to own?
Mat you are the best, that is informative and put to rest a lot issues power hungry guys had.
Nice one Mat, I have been using one of those for a while and yeah, the sound got quite a bit nicer. Performance wise, it felt happier to rev, but nothing noticeable on the road, now I know why.
I also got the semi solid engine mounts recently, found it sharpens up everything slightly but there is some harshness at about 4k which I dislike. Will try slightly softer mounts and see.
Had a carbon clean on my intake,injectors and turbo.Made a big difference.Since the Carbon clean I use V-power fuel and Redex.I could definitely notice the difference.My car stock is 270BHP.Its Had a REVO stage one and now it’s 322.3BHP.Induction kit next week.Great video mate 🏁🏎💨
Reflection Car Care Detailing we re talking about just the filter man, not the entire system :Dddddd ofcourse u feel the difference after full carbon cleaning lol,irrelevan
Max Cohagen I was saying that a carbon clean makes a difference to BHP!
Reflection Car Care Detailing , ok thats true
Thanks for the video. I myself was just considering a K&N filter for my 996.2 which cost about 4.5 times the amont of the stock filter. Ill just buy the stock air filter and do an exhaust upgrade later for my sound/power improvment.

I love your blue on sand beige. Inspired me to get a midnight blue on sand beige 997. Wow car.
Great video thanks for posting.
I love the e36 328i, reminds me of my old 323i years back :)
great video, thanks for upload !!!
Just like my old 328is, I had m50 manifold, simota carbon induction kit, remap, and saw almost the same 230bhp.
The IMS is not as much to worry about if you're regularly running the engine at highish RPM. That's because the bearing was designed to be lubricated when the oil pressure gets nice and high and your oil splashes around with some obviously making its way into the bearing.
Like any bearing (as opposed to a regular transaxle) the IMS does not like to be spun while dry.
Some drop in performance filters save you the need to replace them as often as paper filters. Just need to keep it clean. Maybe a tune will help with the gains from that mod but it may also depend on the car.
More vlogs and videos like this, they are very nice.
I put a K&N performance filter that has an extra air intake "hole" on my 1.6 ecoboost and measured before/after figures through OBD and the kn increases the turbo boost by several PSIs and improved throttle response and sound. I was surprised with the outcome on my car.
The performance filter's major advantage is that it's reusable, can be cleaned and re-oiled. Though I think if it had a tune to compensate for the improved airflow, he would have seen a larger gain over the paper one. The one disadvantage is they don't filter as well as the paper element, which over time will increase engine wear.

Would it need a tune to benefit?... Surely there are sensors that detect the increased air coming in and inject more fuel to match, keeping the ratio the same?
For these older 911's, should keep the new filter and alter the funnel/opening of the pathway from the rear deck lid to the intake box.
If you lived in the states, getting away with High-flow CAT upgrades would be ideal - and a decent tune.
Mat tour standard Ecu could be pulling things back a wee bit. Get a pro remap done with the performance air filter and see the difference. Hope it helps.
Plain oil fed IMS bearing retrofits are available nowadays.
If it’s a oiled fabric type filter, that’s more particulate in your engine oil
i only use K&N or Pipercross filters, they work, save you the cost of replacing the paper one each service (just wash, dry and re-oil once per year), and as you noticed, better sound, especially the models that have the rubber bung at the side (remove bung for warm fuzzy feel). :)
Try fabspeed's dual intake, you'll absolutely love it, esp. The sound
I love these dyno videos!!
I used to own a 328 Sport Coupé just like that - also in Forest Green, I think it was called. I'm on my 7th BMW and have driven many more, and the 328i remains my favourite. One of the last with a cable throttle, which plays a major part in that opinion, but they were also pretty light (same weight as the 996 - around 1300-1400kg). You also didn't get a clutch delay valve or any nannying electronics - just enough tech to make it a good car.
Nice video. A lot of us always wonder about air filters and their alleged power upgrade. Thank you
This is interesting, you should do more videos about this. You have mention the Leon cupra(s3 & golf r) is a performance bargain, how would that be improved with just a quick remap which bumps the power up to 360hp and equivalent torque? Or would it just make it un drivable ?
Finally, I've hoped for this video
More videos on the E36 328i please....
I have a 997 Carrera. Fitted a K@N and for a about 2 years I kept chasing an check engine light. Multiple issues, including vacuum leaks, but the final fix was to put back a standard air filter and put in a new mass airflow. My understanding was the oil from the filter can contaminate the MAF. Either way, this caused my engine check light so beware.
Hi Matt, very interesting test. I would not of thought the outcome would be like that. Btw I like the 996👍🏻
review the bmw 328i!
qUantUmpants yes!
Better than that car anyways
Do it! You'll be surprised how well the chassis handles
e36 328i owner here.. love my car
It's a piece of shit.
Run some expensive fuel system cleaner or ATF in the fuel to clean the combustion chambers, intake valves and injectors, then change the fuel filter.
Most of the restriction comes from the intake tubes so unless you change the intake to a proper cold air intake system with exhaust mods and get it tuned to match you will only mess up the tune and lose power.
High flow filters all let more dust through so the cost of your "sound modification" is reduced engine longevity.
I'm using K&n filter for engine and air cabin but not looking for performance as it reuse after cleaning. I did good savings when using them and cleaning them regularly.
More videos like this , Thanks
Love these sort of vids really interesting cheers matt. (& crew!)
Okay,so here is the thing. I have played a lot around with aftermarket sport filters like K&N,Pilot,etc.. From having experience with Accord Type R,Galant VR and BMW 525i,i can tell you with certain,that the higher you rev the engine,the more you feel the benefits of the sport filter. No,it does not increase your HP.,it can't do that. But allows a better air flow which results in better throttle response and better performance at the high revs.
S.T T. So what performance is it giving if there is no hp upgrade or nm upgrade
J Alcatraz As I mentioned,the performance is not defined only in HP or Nm. Almost all cars come with restricted air flow. To understand what I mean,put a cotton ball in one of your nose holes and run. You can keep the jogging,but if you take a fast sprint,you will find out why air flow is so important.
S.T T. wrong, its just like fake pills for your $ placebo, thats all. but you can give more dirt and oil to your engine....maybe dry filters are not that bad, but the airflow is terrible.
Lmao, hilarious read chap.
@@eleonik76 "performance is not defined by hp and nm" oh yes it is everything car related is numbers. 0-60 power, torque, lap time. Throttle response can be measured. Everything else is placebo. And the the cottoball thing is stupid because you are splitting air flow in half and that also can be measured. Smh
I fitted one of those K&N filters on my 03 C4S and removed it after noticing dust inside the plenum. Sound is great but, at what cost? Anyways, great video as usual @Carwow !
An honest review....thank you
Isn't this the place where Colin (car throttle's M3) was dynoed?
That Guy Yep!
That Guy - I think this place has been on Wheeler Dealer's TV programme as well.
phil's (Car throttle's MX5) first ever dino run was tested here aswell
All of car throttles dynos are done here
The wheel spacers do wonders for the looks on a 996. Highly suggest them as a mod.
We did the SAME test in a VW JETTA 2.0 TSI and we got the SAME results! The K&N in box actually reduced 1-2 hp of the car, but we had a little better fuel consumption.
Great video contributions for the petrol heads out there (such as myself!)
Love this 911, I have drove one , witch hade soft tuning, was accelerating so brutal and nice.
For that air filter, you should had to drive the car for at least 20 miles, so that the computer can make the fuel trimming adjustment. Otherwise, he would not know ,what's with the sudden changes in the air volume.

I think you would need to tune the ecu after an air filter install to see real power gains also you would need to do so when removing cats
CrouchinTiGa unnecessary, there is no significant gain with that perf. filter. but in the meantime u get more dirt and oil in to the engine.
Max Cohagen I don't think an air filter mod is worh the money to be honest you better off spending your money on a decent catback exhaust
Get that IMS done if you are worried. When I bought my 986 S it was on its way out and I put the LN ceramic ball bearing in which had a lifespan of roughly 75,000 miles. I could have done the direct feed but ceramic was cheaper and 75,000 mile rating is fine by me. And I have a 6 year / 50K mile warranty on the new bearing. Can’t go wrong with being safe.
I put a K & N performance air filter in my BMW. It’s certainly feels more responsive and revs more freely but whether there is an actual measurable power gain I have no idea.
stubones look behind the filter shit load of dust
All seems fine. I open the filter box and check out eveything at least once a month. There is no oil anywhere in the filter box aprt from on the filter material. Thanks for the heads up though.
No there isn't, but thanks ever so much for your misinformed concern LOL
zeroyon223 hahaha, that's bollocks. It's an Internet myth. Give your head a wobble, don't believe everything u see on TH-cam.
I've also tested some air filters on my M3 on the Dyno. K&N is the best of the 3 I've tested. I had a K&N filter, an OEM BMW filter and a BMC filter. BMW and BMC delivered the same power. The K&N gives 4hp more! I think he uses also BMC, it looks the same style as my BMC..
You need to re trigger the fuel characteristics map er initialization , drive for at least 50 km , only then you can realize the benefit of the after market air filter if any or any mods that affect the fuel air ratio. For that matter .
I
I did notice after a while washing the k n filters 5-6 times the cotton starts to wear thin and holes appear also my air flow sensor goes bad even with light re oiling the filters went back to standard filters on my e55 amg and happy no more problems with sensor
What wheels are on the e36?
Nice to see the 911 again Mat!
Also re-usable filter. As they can be cleaned and re-used compared with OEM paper filter.
If you over oil K&N, it will reduce air flow and give you lower mpg. You have to make sure it's not over oiled after cleaning
+carwow
Mat, if you want more performance for your Porker, what you need is a performance exhaust system and a remap with the new exhaust fitted. This way the new map will be optimized for the new exhaust system.
Air filters are a placebo for performance but it sounds better. Thanks for the insights! Just saved me buying two air filters for my Porsche.
How long had the performance filter been in for ie was you comparing apples for apples age wise?
Not sure about the 3.4 you have but in my 3.6 996.2 the air filter is simply 7 screws and then disconnect the air intake from throttle body and the air filter goes in and out with no problem.
Try Royal Purple HPS(High Performance Street) oil or AMSOIL.
I'm not an engineer, but from what I understand more airflow turbulence at lower rpm increases torque which explains why the more restrictive factory filter has higher torque. Modern 2 stage inlet/intake manifolds utilize turbulence @ low rpm and free flow at higher rpm for this reason.
Some engine control systems are so tightly engineered and adjusted, putting in a freer flow AF can actually be detrimental to performance, in some cases. Yet, some MAF controlled systems will allow a certain degree of self adjustments to the greater air flow. I put a K & N in my Corvette and my mileage went up slightly. But, I wouldn't put on in my new Mazda3 because I know from past experience it wouldn't do anything. Except for make more racket for less power. Because the ECM can't compensate for anything beyond the OEM filter flow....
Awesome comparison.
I got 24hp gain in the mid range on my 335i after putting in dual cones (car was on an adaptive tune setting).
Great to see the Porsche again - nice car
Would have been good to see other filter types compared as well as the panel filter
@carwow can you review after market electric throttle controller/ booster ? if they're useful.
One thing I haven't seen mentioned in the video: usually the custom filters you can clean (with some special spray) and put it back in, so on the long term, you might even save money (by not buying new paper filters).
Also, from what I understood, they help more on turbo cars, reducing turbo lag (as they pass through more air than paper ones, usually).

282 we are not too far off.
I've seen a 228i e36, same mods and did exactly 226ps like this one :)
I really think you should consider a restoration build, it would be great content and you would enjoy the car much more. Like Car Throttle did with the restoratrion series with "Miles" that was a huge succes with everyone gets a new love for an old Skoda Octavia. Please do this it with be really fun to see the car get in a better shape
5:05 the bonnet badge it popping out of the rubber. Need a larger gasket. Some of the badges are a little larger.
Mat, did you ever get the suspension knocking noise fixed?
Have you thought about doing this same test with a RamAir full induction kit? That would be worth watching.
I've sold many aftermarket air filters (mainly K&N) and I've used them myself over the years. The main advantage (as I always told my customers) is that one never has to replace the filter again in the entire lifetime of the car. Power increase of about 5% max. is espected. Which is not really a lot...
The Porsche! Pleased to see that again. The Beemer sounds a LOT sweeter though.
Really nice vid!
Please try a entire fuel system cleaner with a service with filters and synthetic oil with a additive like Ceratec or Xenun VRX500
OMG, this E36 it's so fucking beautiful, i'm in love 😍😍😍😍
After market filters might also filter less dirt in air ... So how else can we improve ? Intercooler, super charger?
nice video great idea btw😀
Hi So did you get rid of the other porsche you had all the problems with?
How about getting one of them performance stripes or splurging on some stickers; I hear they can give you a HP boost of 15-40hp and Torque by 20-25%. You should look into it.
I put a k&n air filter on my 4s 996 not sure about more power but defo sounded better !
K and n in a 2018 dual jet swift with an exhaust mod and K and N makes a big difference in the higher rev range, seems to have lost a bit lower down, but the car is leaking something nasty from the engine bay so it’s not running right anyway...
Can't you clean the KN one?, which would be a money saving along the way compared to the paper. Also was it clean for the test?
Review the Bimmer pls!
Wait so one minute the wavy dyno line is bad and after it’s dynoed again it’s perfectly normal for a flat 6 porsche?
pendulum1824 yeah, odd how he changed his tone on that one
Was that Paul @ PCW exhaust mods under your car ?
