BlackC230Coupe

not a bad idea.

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.
The site to view is:

i emailed ITG over a month ago regarding ben's itg findings. stuart's assistant(?) told me he would get back to me but haven't yet. i hope you have better luck.

BlackC230Coupe

I hope somehow the ITG filter really does not make u loose HP.

Someone please prove that wrong.

Here's some articles where they tested various filters;

grrr. anyone want a ITG oil filter for 5 bucks? lol

maybe they should have included a drill bit with the ITG air filter.. jk... waiting on the dyno, before i install ...

You didn't hear? The Renntech filters have their new magic cardboard which gives gains over 50hp!

Renntech will overstate their numbers if you ask them.

TXTiger

Do K&N filters suffer from the same design flaw as the ITG filter? Is there hp loss from use of a K&N filter?

Buellwinkle

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.

TXTiger

Availability isn't a problem for the C240 or C320......but does the K&N filter have the same design flaw as the ITG?

totita

Does anybody know if the K&N air filter for the SLK 230 will work in the coupe?

Accord

K&N Filters do not suffer from the same design flaws that the ITG filters do.

young

afaik, totita, k&n does not make a filter for the coupe yet and it is not the same as for the slk.

Buellwinkle

Yes, you are right, the K&N filters have a long history of killing MAF sensors in MBs with their oil at $400 a pop.

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.

I Have Spent Lots of Time and Money $ On Testing Filters
To See What works and what Does Not For The W203 Coupe
I Want To Thank Evosport for the Dyno Time!
If You Want Proof Please contact Vadim @ Evosport

1 The Piper Cross Had SMALL Gains Aprox 2hp..

2 The ITG Lost H.P...

3 The K/N Cone Lost H.P...

Thats Why Im Building a New Air Box/Filter to SEE If I Can Improve the numbers Or Not...

BlackC230Coupe

piper cross makes filters for the coupe?

is their a link to their site? or where and how much are they?

Buellwinkle

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.

BlackC230Coupe

Thats for sure.

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.

Buellwinkle

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.

eason

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.

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.

session

please. i'll switch back to the stock filter if there's any HP loss... a dyno would be much appreciated, even for those of us that don't have a pulley.

Buellwinkle

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.
