'02 C230K
I just sent this to :
<david@itgairfilters.com>
Hi David,
If you have the time, I would greatly appreciate your input on the merits of your product for the '02 MB C coupe 230K. I have you filter, but have yet to install it due to some reservations expressed on a popular web forum for this model. Some contend that ITG's product actually flows less air than a stock MB filter. I do have a pulley kit.

Here's some articles where they tested various filters;

Renntech will overstate their numbers if you ask them.

Accord, the Renntech overstated numbers are what makes you feel good about your purchase (placebo hp or php). Can you find out what the overstated numbers are for their filter so I can feel better. BTW, ITG makes the filters for us to the same exact specs as Renntech, why, because that's the only specs they have for the coupe.
K&N's suffer from an even worse problem, availability. I did e-mail then recently asking if they can help me design a fipk kit for the coupe. With the right design there's 6 ponies at the wheels to be had.

What design flaw does ITG have? I haven't seen any dyno results either proving or disproving their results although I extrapolated a 2hp gain from various dynos done. While this isn't a ground breaking increase it is cost effective at $25/hp. The design flaw that Vadim is talking about applies only to the twin filters in the C32. They have very shallow enclosures and the foam blocks the passage ways in and out of the filter box. This does not apply to the C230. Isn't it funny when the clueless start spreading rumors about crap they know nothing about just to stir the pot. Until a filter comes out that's better than the ITG that's your only aftermarket choice for the coupe.
Totita, no, the SLK filter is a different shape, believe me I tried it.

Mark, were these dyno's done before or after your Kleemann ring? I know you got the PiperCross way before the Kleemann even had a ring. I think if that's the case a new set of runs may be justified as the demands on the airbox are greater with the additional boost.
BlackC230Coupe, the PiperCross is a carbon fiber holder for a cone filter. Costs about $300 last time I checked. Not worth it at twice the ponies.

I think the K&N cone filter lost hp because it is sucking all these HOT air under the hood. If we can direct some cool fresh air to the cone filter, I think there will be a gain. The engine bay in the C230K much hotter then most other cars on the road, the engine bay is too crowed and there is no room for the hot air to escape. I am going to try the K&N cone filter with some air hose to direct the cold air to the filter.

I don't understand how a K&N cone lost power. If I remove the airbox I get a gain of 6hp, 2 ft-lb torque, and that's breathing in air from the engine compartment. If at that point I stick a large tapered oval K&N would that have a much resistance as the factory airbox with a factory air filter? Hard to believe. Eason if you can do it great. just stick a K&N cone where the airbox attaches to the intake runner. Also a short 8" section of 3" pvc with a 45 degree elbow down would extend it enough to put it in front of the air opening in the grill.

I did some cheap custom Cold air intake for couple of cars, all of them attached a K&N cone filter, then I use a flexable air hose (from 2" to 3" if rooms allow) to direct air from either the front or the bottom of the car, this can help to draw some cold air to the cone filter; therefore, the faster the car travel, the more cold air rush into the intake. I will have a try tomorrow, I don't think it is very difficult for the C Coupe, since the air filter is very close to the front grill. All I have to do is to find a long and narrow K&N cone filter.

Fast Cars!
i got my ITG air filter today and i put it in like 3 hours ago.
I did not drive the car since its in but i will tomarrow.
I did rev the engine a cupple times and i could almost swear it sounded a little different. to me a little througter.
i am not sure if its just in my head though because its hard to tell with my exhaust.
i was planing on looking if i felt any tiny gain when i drive it, but just knowing it lost 2 hp makes me think what did i even put it in????
not to mention waste the money.
i hope that someone will do a dyno again and at least see a 2 hp gain.

But if you want numbers, the difference between factory and no filter was about 6hp and the difference between factory and ITG filter was about 4hp. So my guess, although hasn't been directly proven is that the ITG filter is good for 2hp gain. Can the filter be improved, absolutely there's potential but I think the next step is a K&N cone filter on a tuned intake tube in place of the airbox.
Like I said before, I'm more than willing to try another dyno to settle the issue.

If it's any consolation, I beat out a '92 Firebird TransAm today. He stood on at the green light spinning tires for what seemed like forever, not smart across the street from a hospital. I was neck and neck until I hit 3rd gear and then I got 3 car lengths ahead of him.
I'll try to do a dyno in the next couple of weeks. It's tough to justify a $75 dyno run for a $50 filter.
