K&N High Flow Air Filter Installation
#26
It was a 6 speed with just air fitlers installed.
Default Mercedes C300 is 228 horsepower and 221 lb-ft of torque.
When he did dyno results were 241 horsepower and 229 lb-ft of torque.
At the wheels he pulled 207 hp and 196 tq.

Oh no (ducking head), here comes the dyno "discussion" again.
Some motors come stronger than other motors, straight from the factory. Same model, same motor, but one can be stronger than the other "naturally", let's say. All numbers published are just that, little numbers on a sale brochure or in little pixels on your screen, not necessarily real in the sense that it has much to do with the specific car YOU own (not to mention all the other variables that are involved in dyno "results").
A lot of discussion, on a lot of forums, concerning a bunch of different motors, some daily drivers, some special purpose, have gone over the K&N issue. Some swear up and down that they free up obstructed air caused by a factory design, while filtering effectively. Some just swear at them (the filters) because they've done nothing, or clogged the MAF, or let more grit in, or whatever their argument has been.
I personally don't think MB, with their engineering and longevity reputation on the line (not to mention having to comply with CARB here in sunny Calif) is going to simply muck up the intake design to save a few bucks and be a little less compliant with the law.
So why think that oiled guaze is much different from dry paper? Advertising, in the media and by word of mouth, many times from mouths that don't know much about the pros and cons.
I will leave you with this: I once, on my absolutely last road trip for hotrod mods several years ago, drove a car to SoCal, and had a blower and associated electronics installed, buy the guy who designed the whole kit. The car was dynoed after that. He's one of the better known names in import modification, had his own dyno, and has done design R&D for Honda Japan. He's raced, and he knows what he's talking about. He assured me that putting a short pipe intake and either a K&B or a foam filter on the end of said intake would free up about 10 horse, and better yet, a bit more torque. He put it on and away he went. Know what? NO difference. Not with the short straight through intake, and not with the filters.

The whole idea of the K&N filter ruining your MAF sensor is silly. I spoke to customer service at K&N and they told me that they have had claims about this happening but have not yet had any proof that it was caused ny the filter. I have had K&N intakes on every single EFI and carbuerated vehicle I have ever owned and have not had a single issue with a MAF sensor. The thing I find funny, is that the guy who initially brought this up (about the oiled filters) has BMC filters listed in his sig. WTF?

Where did you guys order these K&N filters? I'm thinking of getting one and DIY.
I found this on Ebay, do you guys think this will work?

Supposed to be every 50k miles, but it really depends on area and situation. I know several that change it every 30 that live in dusty/rural areas. If you're in california, you change it after every wildfire in your area :p

i clean mine once a yr (after summer). it is particularly dusty where i live. take your environment into consideration as to when you clean it. if its really dusty, clean them more frequently.

+1 this is one of those things where I'd stray from cookie cutter book recommendation and apply best judgment rule. Base your care off your environment and examine your filter from time to time to see if it needs changing.

I just installed my K&N and I had the same problem with the filter making the intake housing stick out. I did a little NIP TUCK and that fix the problem.
AutoZone is where I got mine...

I got mine off of Amazon ... I think it's cheaper than ebay and more trust worthy...
After reading about the MAF possibly being effected by the oil on the K&N overtime..it's making me think...hhmmm....I'm closing in on 50K miles...and the filters are on their way ...

I put K&N's in my 2009 C350 and the check engine light came on within 20 miles. I replaced them with the stock filters and before the end of the day, the car cycled and the light went off. I returned the filters and picked up some oem style and no problems. This is the first time I've ever run across any issues with K&N.

I have used advanced aftermarket intakes and filters on other cars that were not engineered to the level of my CL or my M113.
The idea that MB would not use a superior intake and oiled filter technology in an AMG if it were better performance wise is quite doubtful.

Guys, i appreciate this information on installing K & N Filters for the C300, nice photos alos!. To C-Class_Greek, these filters really do help the car to breathe better that the paper as the K&N use cotton for the filter material and it is much less restrictive and produces much less turbulence than the factory (paper) filters. I had k&N in my old 1997 C230K 5 speed stick and there was a noticeable improvement in acceleration.

leave the stocks in there like posted previously. I have upgraded filters and the only other than OEM I would use is BMC. they are pricey but are the only ones AMG tuners and the like use, they even make ur motor growl a little more on the intake side........

Agreed... I threw my K&N's away for this reason.... and I installed a set of OEM MANN filters purchased off of Amazon Automotive for half the local jobber price.

I did the same install an yes you need to trim a little bit, as far as horsepower gains i couldn't actually notice any power increase but i don't know in a Dyna.As for price i bought them @ pep boys and got a better price than amazon and ebay but i dont know if at that time they were on sale. Nice install

This is one heck of a roller coaster of a post on air filters...
K&N - OR - BMC - OR- OEM?
All the arguments are legit on both sides...
However, what I want to know is if there is anyone that actually had sensor problems due to the oil from the K&N? (Other than RichardA)
Update: Ok so here's one very interesting blog post with people with all different makes reporting their problem, but it seems that the problem may reside in improper re-oiling which may cause this ...alleged problem?

I have K&N's on their way and am curious if I should send them back...
