i have a k&n filter now and came across this article but i'm not sure how much of it is fluff paid for by gm.

if true this seems disturbing to me.


"in the chart above it’s important to note the different test durations for each filter. The AC Delco filter test ran for 60 minutes before exceeding the restriction limit while the AMSOIL and K&N tests each ran for 20 and 24 minutes respectively before reaching max restriction.

In 60 minutes the AC Filter accumulated 574gms of dirt and passed only 0.4gms. After only 24 minutes the K&N had accumulated 221gms of dirt but passed 7.0gms.

Compared to the AC, the K&N “plugged up” nearly 3 times faster, passed 18 times more dirt and captured 37% less dirt. See the data tables for a complete summary of these comparisons."

I think the problem is two fold. First, the K & N has to be cleaned and oiled every so often. Hyundai dealers would stay away from that because any error in cleaning would possibly invalidate 100k warranty on their part. Now 2nd, think about the average guy ( not you Of Course!) doing it in his back yard with his hose and oiler. Think of the possible problems that the dealer would have to reject if under warranty for any MAF, etc., malfunction because of over oiling and not draining it off. This could cause serious problems even according to K&N. Also some would probably just leave it on forever with out cleaning( since after oiling they are not white, can't really see dirt until really dirty/clogged). None of this would happen to us since we are car nuts, but most owners are not. None of this make sense if you are Hyundai offering under a good 100k warranty. My controlled back to back dyno tests do not reveal any large gains from the K&N. My results showed less than 2-4 hp difference & my paper filter was not new. It of course made more noise, great.

Everyone knows that one's car runs a lot better after it has been washed and cleaned inside. The same goes for K&N air filters.

Yess lmao... so im not the only one. I swear the car knows you washed it!!!!!!

What? Someone that actually performed a dyno test with an K&N filter on a Genesis?

Can you post your test data please?
