I desnorked many years ago. Never had an issue. There is a wall between the snork and the engine compartment - this in addition to the air box itself. In the day, I researched this extensively. The only rationale that makes sense is that the snork was inserted to reduce noise for euro specs. The other rationales just make no sense once you look at the set up in the 986. I submit there is a noticably deeper intake sound. For my part, I felt it was worth the MASSIVE investment. Is it night and day? Nope. But again, the price is right.
Full disclosure - I broke the foremost clip on the colored portion of the finned cover. I used epoxy to repair and never had an issue. Many of my friends also desnorked at the same event. None ever had a negative experience.
Is that evidence anecdotal? Yup.
Can you reverse the job? Yup - one friend put it back to sell the car.
+John Morgan yes, pretty much exactly my thinking as well.
@@HelpMeDIY For the record - I am convinced that I get a .00005 hp gain too. Just ask the butt dyno.
Well put
Great video. Not sure if anybody has talked about this. As an engineer thinking of physics; when you squeeze or have a tube that is smaller it will increase the flow when pushed through or sucked in this case. Thinking of water flow and sprinkler tubing, when you decrease the diameter it will make the flow faster and go farther. Understanding the thought process for more "free flow air" or sound, I say keep the snorkel because it's sucking through the right sized tube. Those German Engineers deserve some credit.
+Jeff S that would be true of the water if the same amount of water was being forced through it, but if it was just flowing over a smaller tube then less water would go through. I think that scenario would more closely match.
@@HelpMeDIY I see your point. I guess it might be determined by how hard the flow is being forced or sucked in? Then the diameter would matter more is what I'm saying. Think of pulling at 2500 rpms vs really sucking @ 6000? But then again you're trying to get as much air as possible. Interesting. I'm wonder if there is a way to test this by the MAF? Maybe on a dyno?
This was the first mod I did to my 986. I noticed, what I think is a slight increase in the sound of air being sucked in under acceleration. Definitely no problem having any foreign bodies getting through as I noticed a fine mesh in front of the snorkel, which I left in place. Great vid as usual. Thanks
+Robert Hooles seems to be a popular first mod! Glad to hear everyone reporting no issues.
Desnorkeled mine years ago also. Love the sound. Have had zero issues.
+Shaun Stamnes love to hear it!
I cannot believe I have had my 99 since 2014 and had not seen anything about this. Just did it and what an improvement in sound. Thanks Aaron! Maybe I’ll run into you at a PCA event in NC.
+Carrie Stopka you’re welcome! I’ll be at VIR on Saturday with the PCA…
+Carrie Stopka hey, you should subscribe! 😉
Did this to my wife's 2000 Boxster S and we definitely hear an improvement.
+G F yes!
I removed the snorkel, drilled about 10 1/2" holes in the top and reinstalled. Better sound and still helps prevent water from entering air box.
+David Dapra interesting approach!
That's a pretty neat idea for something that is basically free. But I went ahead and got the Valved Muffler Bypass Conversion, and the car has a button to switch between the stock and the really loud bypass. For anybody looking for that extra sound in their 986, I would recommenced the Soul PP one.
+pr0d1gy visions sounds like another good option. Thanks for sharing!
I like that you confirmed you could put it back into stock condition 👍 i'm going to try this desnorkeling idea.
+Baupylypuab thanks. Hope you’re a subscriber now 😉
Oh, yea also, I removed my entire air box about a year ago and put in a cold air kit and I love it! I did do snorkel first but move a step further to a cold air kit and BOOM its been so nice ever since.
+Daren Maglione it really makes a nice difference!
I just bought a 2004 Boxster S 6-speed, midnight blue exterior, medium gray and black interior, with 87K on the odometer. Happened to see your video show up on a TH-cam search. I mainly wanted to see how to remove and reinstall the side vents, I have one that is loose on the bottom edge. Thanks for the bonus info, I'm going to try the desnorkling mod. I'll prolly get some of that double sided tape first, just in case. I'm now a full fledged subscriber. thanks for the vid. :)
+Scott Shrader welcome aboard! You found the right channel for all Boxster owners 😉🍻
I did mine a few weeks ago and immediately as soon as started, I noticed a big difference in sound.
One of the very first mods I did to my 99 boxster base.......Doing that coupled with my K&N I can hear that throttle body sucking in the air.
+Riley 1955 💪
Did this on my 2004 986 2.7 and got a check engine light after a few days and lost a bit of low end torque, reset it and same again a few days later got the light again, put the snorkel back and never an issue again in the year and a bit after I kept it before getting my 996. What you need to remember is Porsche make sports cars, it’s not a M series BMW or a golf GTI ect making a passenger car sporty where compromises were made to adapt an economy and cost focused car a sports car Every aspect of a Porsche sports car was engineered from day 1 with performance driving in mind, your intake is already a cold air intake with a large low resistance filter. Taking your snorkel out to suck hot air in off your engine isn’t going to do you any favours. Hot air means less power and worse fuel economy. If you want better sound then. Buy the sports exhaust
+Ben Terry since you have done this before you should know that no additional air from the engine compartment is allowed in without the snorkel. And yes, this WAS Porsches “cheap” car made for the masses to allow the company to survive (and thrive). If you think the stock suspension, for example, is anywhere near the level of performance as the aftermarket (non-Porsche) Bilstein PSS9 suspension, then most of the rest of the world and I will disagree with you. ALL car manufacturers make decisions on how to make money, or they would only sell GT2s. I hate that argument
@@HelpMeDIY The temperature inside the compartment the air is then drawn from doesn’t have fresh air flow and heat from the engine radiates through the bulkhead and keeping this air warmer that externally drawn air. Also Sports does not equal track, you can do a lot to a car to make it better on a track but it doesn’t make it a nice all round driving experience. PSS9’s are not a comfortable replacement for stock bilstien b4’s for sport and road use and suit only a tiny minority if people who want to deal with setting them up. But regardless here you are not adding a improved part you are tearing out a part that specifically designed to draw cool air in from outside you car and claiming air warmed up by your engine and exhaust stagnant in this compartment is better than air from outside. It's your choice what to do to your car but objectively you have only reduced performance for vroom vroom noises. Porsche's cheap car for the masses still cost more than an M3 at the time it came out, a cheap Porsche is still an expensive car and Porsche pride themselves on engineering and a precision driving experience, every component has purpose and has been tested for that purpose.
@@benterry2681 there is a wall between the snorkel opening and the engine compartment, not to mention the air box itself. If you want to think Porsche components are perfect and can’t be improved then idk what to tell you 🤷♂️
Yup. 1st mod I performed. When I see the driver in the car ahead flicking ashes, I either change lanes or pass them lol
+Guy Spaulding haha good plan
Hey Aaron - I'm also Aaron and I just bought a red 986 S yesterday! Looking forward to your advice via the channel!
+Aaron Windmiller right on! 🍻
thanks for this video, the explanation of the cons and the debunking of them was thorough!
+A L thanks!
Love your channel. Got my “ l am the warranty” black t-shirts in today. 😊😊😊😊😊😊😊😊😊
+Scott Shrader thanks for your awesome support! 🍻
Did on mine and love sound and with my fabspeed intake kits.
Did mine 2 years ago. I think there is a definite difference.
+Wild West I agree!
Thanks for the video, I would keep my snorkel as I look it as a cold air induction pipe with a deisgn of hydrolocking protection.
What I have done is remove the foam on the stock air filter which the power increase is noticeble and little sound too.
+TIM Cheou you’re welcome
Super easy to take off after watching this video! I saw how it can be difficult if you don’t know how to thanks!
+calvin hernandez yessir!
So cool. 'Did not even know of this. 'Always have wanted a bit more exhaust presence, so to speak!
+Joe Pfister enjoy! 🍻
I have not did the "desnorkel" yet but that is on the to do list for spring. Nice video no B.S. just to the point.
+otter25702 🍻 Hope you’re a subscriber now 😉
Done this to mine after seeing your video very informative and works a treat 👍🏻
+EAST PRESTON CLASSICS enjoy the sound 😎
Going to do mine,have a sports exhaust inc manifold,get a drone at 2800 to 3 k,annoying says the wife,I'm used to ducati s so don't mind,but good job with the paint,shame they didn't stuff some paper in the intake hole,(I do my own paintwork ,ex painter retired),thanks for the info,well put together.
+Everett kirk love the sound of a Duc!
I did it two days ago - it was like 2mins job and it does sound amazing!
Btw. My 02 Base Euro snorkel is different. It doesnt have that "cup" and has mesh on there instead.
+jagymeister that’s interesting. Glad you like the sound!
i bought a used S that was desnorkled. A LOT of dirt was in air box and some got past the air cleaner and into the engine. The throttle body had a thick coating of dirt on it. The engine compartment was very dirty so possibly it frequently was driven on dirt roads. I believe if the snorkle had been in place this would not have been as bad.
well, I just fixed the passenger side vent with some handy dandy 3m molding tape, not loose anymore, but while I had it out, I noticed there's and electric fan behind there, also, my drivers side vent has a screen behind it. so the passenger side vent does serve a function , as does the drivers side vent. mines a '04 S
+Scott Shrader 👍
If it actually breathes more easily it will maybe also need a retune with more fuel in the air fuel mixture? I de "snorkeled" my KTM 500 and got the full power tune installed for the engine, that really have effect, from 15hp to 58hp or so... (All KTM dirtbikes is restricted from the factory in the air intake to reduce the HP for import tax).
Did the same thing myself and it was a noticeable difference especially after making an exhaust change. Next project is doing a hi-flow air intake.
+Fred Noce good luck!
The snorkel really didn't stop my car's previous owner's cigarette butts from getting in the airbox
+samin90 doh!
havent done it before, but was curious. was always too scared. Might have to try just to hear it! I did notice the sound change when I threw out the K&N filter the previous owner put in, and went back to paper.. got a lot quieter, def sounded better with K&N
+James Zilla this will probably get you back to the K&N sound. I’d think even louder.
My recent purchase (and first Porsche) has been desnorkeled. I want to put snorkels back in to reduce the sound level. It has an after-market exhaust (very loud) that I am in the process of buying parts to return it to factory spec so I can have a quieter car.
+Mark Cash some like loud, some like stock, some like in between. Make it yours!
Really nice video, thanks!
What exhaust system did you install?
+Jonathan Koppelman you’re welcome! I have a video of the install... I went with the $250 eBay special!
Great video! Where did you get your PORSCHE lettering below your spoiler?
Thanks! I got it from my buddy Aaron at RennPart. It’s an official Porsche part.
funny thing is in the UK its the passenger who gets the benefit not the driver. I havent done mine yet.
+Chris Moseley oh that’s true...
I'm a new Boxster owner , quick question " did your chk engine light came on after taking the snorkel out"?
+@ricorbe586 no it should never cause that.
First mod I did and I love it :D
+TheXbaT 💪
@@HelpMeDIY Do you got a video on preformance air filters? I am wondering if the K&N replacement filter will make more intake sound? 😁
@@theXbaT1 no I just have the stock air filter. I’ve heard negative comments on the aftermarket ones that suck in hot air from the engine bay 🤷♂️
@@HelpMeDIY Yeah i Know, but I was thinking of the K&N replacement filter that fits in the original airbox
The dirty side duct (snorkel) is a tuned length and both the intake and exhaust are tuned to meet drive by noise regulations. So by de-snorkeling you are definitely changing the length of the dirty side duct and it will have an impact on the engine order noise levels...
As a professional automotive engineer I’d say you’d probably suffer upheat issues and have high intake air temps... particularly on hot days after a hot soak...
I have a 99 986 and still not sure whether to do this... but sound quality is a good thing and noise regulations are generally a bad thing for sound quality and level...
+Paul Riggs what sort of heat issues and why, specifically?
Curious about this too
Great video thanks! Hey by the way where did you get your "gear type" center wheel caps! They are awesome.
+Daren Maglione thanks! I have a separate video on center caps and explain it there ;)
I owned my 98 boxster since 2000. I also have a cold mass air installed and a 3.4 996 engine swap.
If I drive for 30min or more in the rain ,the car starts shaking.. if I don't pullover check engine goes on.
+Ali Alrashidi very interesting 🤔
@@HelpMeDIY I think you maybe ok since you have the factory air intake (not sure). In my case I had to go with larger air hoses and cold air intake (so the engine can breath better). I went from a 2.5 boxster to 3.4 996 engine.
Also had to remap ecu (using 996 software) and upgrade exhaust system.
Everything works well.
I think it's better than a turbo or supercharger.
It feels like I am driving the same exact 2.5 engine .. but a little louder and a lot faster. Makes it a bit more fun.
The 2.5 is tons of fun as well no need to upgrade but once you get bored I think 3.4 or larger is the way to go.
Bytheway..still very economical. Solid no issues since 2000.
Oh as I said the boxster is a 98 ,the upgraded engine is from a 2000 ,996 engine.
@@HelpMeDIY as far as drivability it is the same fun in 2.5 and 3.4.
Just quicker and more juice in 3.4.
Oh yeah I also upgraded the suspension. Stock is wonderful. But I like a stiffer ,rail road like handling (coil overs). Which lowers the car...so I got 19x 10.5 rear , 19×8.5 front wheels.
Drives wonderful.
997 GT3 front bumper (It fits better with the larger wheels and lower coil overs).
@@alialrashidi1764 sounds amazing!
@@alialrashidi1764 Ali, I just bought some tires and wheels for my 2004 Boxster S. The rears are 18x 10.5. What kind of spacers did you use for both the front and rear. Any issues with the strut or brake hose?
Curious question: The intake manifold gets it's air via the snorkel, the air from the side of the car, but if the snorkel is removed, would that mean the air is now being sucked in from the side vent and from around the engine? Where I'm going with this is, would desnorkeling cause the air filter to get dirtier, quicker with the snorkel removed?
I'm brand new to Porsches, admired them since 1985, but I just bought my boxster a few weeks ago.
+Scott Shrader that’s a possibility
I alway go with this school of thought. If Porsche didn’t feel it was necessary to have it there, why would they design it that way. Do what you want, it’s your loss. The real question should be, how good is it if your body shop guy sprays paint inside your engine?
+Bobster986 a lot of people agree with you. You have to remember that emissions and other regulations as well as cost savings play a huge role in production automobiles and many decisions made my Porsche (and all auto manufacturers) are driven by those instead of what is “best”.
@@HelpMeDIY just so you know, it looks as if your snorkel was removed before you got there. I can see many other part that make it important to keep it the way the factory designed it were missing. Like I said before, it’s your car, your loss for some mod that hurts more than it help.
holy red spray can, batman!
+John Poo you would think so wouldn’t you… 🤦♂️
100% you hear it under load. You can hear it coming from that vent even.
+@ryanm9546 👍
my boxter has hissing sound from right rear side while driving. recently water pump replaced. it made air coolant leakage. is it related ? how do I fix the issue?
+Wowwow your coolant cap might just be loose or possibly needs replacing
@@HelpMeDIY Thanks for reply quickly.
but why this is related to coolant gap??
@@Wowwow-wl3kx just a suggestion on something to check. Impossible to diagnose remotely
@@HelpMeDIY my coolant cap replaced with new type when porsche replace waterpump.
I opened coolant cap it is closed properly but a little pressure on it.
it seems coolant is not enough.
do you think it is related lack of coolant??
Con: if you run your de-snorkeled Boxster thru a car wash, water up into your airbox?
+@sgrowe56 if you run your Boxster through a car wash you probably have bigger issues 😆
help me I have a porsche 986 and all the cluster instrument lights are on, what can I do?
+Reimar Cortes hmm that’s never happened to my so I don’t know, sorry. I have a video on how to use the Durametric tool to diagnose codes if you happen to have access to one, but not sure the issue would be generating a code or not.
Just bought one today 04/20/21 2001 model. The alternator went off line on the way home. But the battery light didn't come on immediately. I did notice while the battery was loosing power, I started to collect dash warning lights. First the ABS, then Airbag, hood open...etc. I checked the diagnostic codes on all of the modules before the purchase. All the codes were for low battery. I thought it was just from sitting. Likely not. Don't care. I like to wrench and paid $5k for 83k mi!
So... your lights might be originating from low voltage. The engine looses power at about 7.4v. Amazing really. I am an Auto research engineer in Detroit, help design many autos. American cars are typically designed to stop at 9v.
But I digress. Put a volt meter on the fuse panel, cig lighter or battery. Make sure your voltage is up.
Have fun! M
Check with diagnostic tool.
I love your videos but this one has a problem for me. I'm 2 minutes into the video and still don't know what "desnorkeling" is. Maybe you could have started with that. I'm not just a pia kid. I have a 986 and am learning how to do my own maintenance on it. I'll do some research and get back to this one when I know what it is about. But thanks for teaching us about the 986. A great car and which doesn't get the respect it deserves. This of course is always people giving their Cliff Claven unschooled opinions. I've found no on on the internet who has driven a Boxster of any year who doesn't think it is an incredible machine.
+William Potter thanks for the feedback! I guess I should have started with defining that slang term many Boxster owners use instead of assuming everyone knows what it means. I hate it when people do that. My bad!
The shape of the snorkel is designed to speed up air flow. If anything, I believe you’d loose power…
+Roland Rohrle I believe it’s more noise emissions related…
Couldn't remove the outer casing and ended up damaging the paintwork. Very difficult to remove so I gave up
+kev card yikes! Sorry to hear that. I heard the clips can be tricky and I assume that’s why mine were already broken 😞
Someone should do a dyno run before and after...too much conjecture. I'm planning to desnorkel and see what happens...I'll let you know my opinion after.
+DIY life in Japan let us know
What spoiler is that? Do you have a video of you installing it?
+Tuned Joe Toth. Kind of... I have a video on removing the old one and one on the Joe Toth spoiler.
If you have an 2004 Porsche Boxster S 550SE (1953 were produced) there isn't a "Snorkel" to remove as the air filter intake is the same as an 2005 Porsche Boxster with a "Round Donut" Filter instead of Flat, Just for info.
+Charles Romain cool thanks!
Thanks, just bought this version.
Hello! Where did you purchase your tail lights?
+CJ 2 got them on eBay. I have an install video for them and there is a link in the description
I'm on the fence with this one , Porsche wouldn't have fitted it for fun ?
+Mike G all car manufacturers do lots of things because of governments, including noise, pollution, fuel economy, etc. so no, everything they do is not gospel 😉
@@HelpMeDIY Yep , I can't argue with that. Maybe it was to minimise drive by noise or something ?
@@mikeg8835 I’ve never heard a definitive answer on it 🤷♂️
Oh man I was so excited to see a desnorkel on a 1998 like mine! I've tried to take off the outer trim before unsuccessfully. After you remove the screw, how do you undo the clips? Do you just pull hard?
+Patrick Linkous sadly as you saw, mine were already broken so I couldn’t show you. I’m sure there is a science to it but yes, it just pulls out.
Patrick Linkous you have to very gently slip each clip out as gentle as possible as they are made of very brittle plastic.
@@porsche9869 How do I slip the clips out? Do I need a tool?
+Patrick Linkous I’ve heard of people just using a flathead screwdriver to help push them out.
Patrick Linkous when I removed mine I just gently wiggled each clip out with my fingers as a tool would likely damage the clips. The only tool you should need for the job is a small Phillips head screwdriver. The later models 03-04 had a screen that you would have to remove to get to the snorkel. If you have an 03-04 car you will also need to undo the Phillips screw holding the screen in place. Good luck did mine about a year ago and have never looked back love the louder and deeper induction noise.
first. Never happened before
+John Morgan 😂😂😂. Thanks for making me feel like a real channel. I see that all the time but believe it or not you’re the first to do it on one of my videos. Actually had to read it a couple times to get it!
Different subjects have a boxster 986 2002 and and it smells like smog where is my problem
+@benstout1402 sorry I’m not good at diagnosing, even if the vehicle was here 😆
When your washing your car with a high pressure hose water will get in
+Mr Porsche you shouldn’t wash your car with one. I use a foam canon.
When I wash mine I just dont drench that area simple and my 986 stays pretty clean anyway. Just take to the power wash to clean the bugs and slight road grime off.
It is not the original screw
+@dr.conradg355 that wouldn’t surprise me
Meh. We are in aftermarket pod filter territory here. Rarely any improvement to find.
+Morten Kristoffersen only an auditory improvement. But I like it.
5:26 - 6000 RPM with a cold engine? 😬
+@rickheagerty5483 it wasn’t THAT cold 😆
First of all I like you channel, good info. I have a 987 and ended up designing a cover for the 987 after desnorkel (th-cam.com/video/paGo_KYmr2k/w-d-xo.html). For the 986, as I saw in your car, there is no mesh cover inside; but it seems that Porsche placed one on the 2004 forward 986 models. You can see on your video the hole to attach the mesh. If anyone has this mesh on their model I would like to have an outline of this mesh so i can complete the process and send you a sample for testing.
That would be cool. Hopefully someone that has the mesh can contact you. I’d be happy to make an install video for it!
My 2002 Euro 2.7 has a mesh there.
#gogators :D
+Eric Zeger chomp chomp!
