Just got a K&N replacement filter element for my CLS. I noticed that it has about half the surface area of the stock filter. The stock filter is about 2 inches thick (fold height) and the K&N is about 1 inch thick. I know the K&N material flows better, but with half the surface are am I gaining anything? Anyone have experience wiht this?

They only thing you gain with a K&N drop in filter is the million mile warrenty. You get basiclly no power gains, you just never have to repace it

you'll gain a little power from it. Your gas mileage will also improve

my gas milage noticably improved.. and wish the price of gas, that's a huge bonus.. well worth the $40 ...

Okay, then maybe it is worth it for the mielage and maybe a slight power gain to boot. I did not go with an entire airbox replacement because I was worried that I would not like the increased noise.

then the K&N is the perfect option for you

gas mileage and about 10%~20% louder @ WOT

Did you look into the comptech icebox? The noise isnt much louder than stock w/ in vtec.

i dyno-ed 23hp to wheels extra w/ the K&N ..

You are kidding, no?

an air filter will gain 23HP to the wheels?

I (as well as the rest of the people reading this thread) want to see a dyno chart!

wow plz i want to see ur dyno b/c I feel nothing on my car

nicer at wot when filter is new/clean

cheaper then replacements over the life of the car

better mpg

overall pays for itself

if you want extra power, remove the resonator and reset the battery. it will increase the air flow to your K&N filter.

1000 dollars says the k&n doesnt improve 23 hp to the wheels, much less at crank.

maybe he meant 2.3

Thanks for all the info! Anyone else notice thet the K&N replacement filter is louder than the stock filter?

yes, just a tad at WOT

Thanks

is that Legend420 who said 23hp at the wheels with the K&N Drop In?!!???

tltype s, show us the dyno. just a bit skeptical....

How much louder without the resonator? I have the K&N drop-in and I have only noticed a marginal improvement in gas mileage. As for HP or torque I couldn't tell one way or another.

tl type S

what did you dyno?
