K&N Air Filter
I have been looking to replace my air filter on my 2002 c230 coupe and I have looked on K&N website they say they dont have a match where can I find one?

On K&N's website. It's a little cryptic.
On the applications, you choose "2002", then "Mercedes-Benz", then "230" (don't choose "230 kompressor"), then 2.3 Liter. It's part # 33-2193.
I just put one in my car. Be warned, though - lots of nervous nellies on here will tell you that OEM is the only filter to put in your car.

I put a K&N filter in my car and within 75 miles I get the cel. Dirty MAF. Coated in the filter oil. This was, for once, not user error in terms of over-oiling the filter when servicing it. Vast number of people are having trouble with k&n products due to over-oiling the filter and then soiling the MAF sensor. But for me, it came over-oiled from the factory. There was a puddle of it in the packaging.
Just warning ya. You won't feel a difference, anyway, all placebo. The only up to the K&N is that you don't have to keep buying new filters, but after my run-in with a near death experience for my MAF sensor, I'm going to stick with paper.

Also its been dyno proven that K & N filters did worse than the stock filters

I also remember someone testing with no air filter and the results remained the same! I also believe it takes a very controlled room....temp/air flow/load control and sensors everywhere.... to get valid dyno pull comparisons. A car sitting on rollers in a garage with fans in front doesn't produce what I would call repeatable statistical accuracy when you're only talking about a couple of hp difference.

I'm much too lazy to try to find it again, but when I was looking at replacing my Green filter last week (it had totally disintegrated when it was checked, it was pretty amazing), I did some searching on here, and I do think that Buellie did find that, on the M111, the K&N did add 1 or 2 hp. Obviously not statistically significant, but I do like knowing that I don't have to buy another filter til I finally upgrade to a Z2, Mini Roadster, 135, or 2nd Gen Z4 M Roadster in a couple of years.

Just stick to the standard filter. No Micky Mouse dyno has adequate resolution to read 1 or 2 hp reliably.

well, a gauze type filter i.e. K&N, BMC, Green, etc does flow better than paper filter. however it's also know that it does not filter as well, but we're talking about micron of particles. unless you constantly drive through some desert storms daily I wouldn't worry about it.
as for dyno numbers, it depends on the car and how it is tuned. a fan in front of the car while doing the dyno is simply not enough to simulate real environment. a clean and just enough oiled K&N vs clean paper filter the K&N will provide better flow.
at least for the M272 the real reason for gains is because the oem paper filter sits and blocks about 2/3 of the air intake inlet to the airbox. The K&N does not i.e. provides more flow.
as for damaging the MAF. I've never experience anything like it. I have the BMC on the 203 and the K&N on the 204. our family beater 97 528 also had K&N since new the MAF died of rightful age, not from over oil of the filter.

My .02 on air filters.....
Not trying to start an argument but......
The real question is.....can the motor take advantage of it? No. If something as simple to engineer in at the beginning of engine development like air filtering would add even one hp the engineers would do it.
The MAF is not a normal wear item. Usually particle blasting or chemical contamination damage them. Engine abuse like lots of stop and go, peak rpm use, heavy loads, etc. can let unused fuel accumulate in the intake ....like that goop around the throttle body flap....and possibly make it's way up to the MAF as well. But usually most people never need to replace the MAF - except for those that have over oiled filters.

If they did, the C class intake system would be much better thought out, I'd hope.

I know changing filters and pre filter intake tracks is popular but unless you're going to cool the air charge more I think people are wasting their time, money, and affecting reliability. But I did they same thing 'way back when' so I''m not knocking it. Just saying.

the MAF in the 528 died after some 150k miles + 13 yrs in the sun. I just recently replaced it. like i've said, it had nothing to do with the K&N.

Mark - You & I have made a reasonable argument for proper filtration. If people don't want to listen - so be it.
The only way to achieve reasonable power gains is to improve volumetric efficiency of the engine & drop IAT to lower levels. This would achieve better cylinder filling with more dense air. To do this would require a complete inlet system & airbox redesign.
If anybody has an opportunity - they should watch the Cummins training movie "Operation Hourglass". This shows just how little dirt/dust it takes to destroy an engine. About one heaped teaspoon full over time.

hahaha good stuff guys. I don't even get into this argument. I remember I mentioned this and a sponsor came and "proved me wrong" and then sold a K&N filter to some poor guy on this board. Milkman has K&N and he said he hasn't felt crap (you guys can add that to the list too). Save your money and don't send the Grim Reaper to your MAF.

Sorry guys. Owned my car since new. Used K&N for more mile than stock. I'm at 218k now.
Huge respects to the authorities here, but K&N and a recharge kit. Done.
