I have a 2003 Evo that I put a K&N air intake on and it runs worse now than it did before with the stock intake. Has anyone heard bad things about whether K&N intakes work well on an Evo? Any insight would be appreciated

 

If by "K&N intake", you are refering to the infamous K&N Typhoon intake system, then definitely get rid of it at once as it is a patented POS and will make your Evo, or anyone else's, run like garbage.

 

I got one since I bought the car, previous owner had it on. But of course it probably had a tune.

I don't have any problems with mine. What is happening?? If it is stalling, check the connections after the MAF.

 

There is a "filter shootout" somewhere on here, and K&N was the worse performing filter of the lot....

 

^ that sucks, I was thinking of getting one but I guess I won't now I've always liked K&N had them pretty much in all of my previous cars

 

If I recall the typhon messes up the readings of the MAF

 

its either get rid of it or get it tuned.

 

Get a Perrin filter! They work great, and they look cool as hell too. and APR all of them are discounted

 

get rid of the K&N everyone is giving you the right advice. The K&N sucks for the Evo.

 

I agree with everyone else, kn sucks. I have an intake for sale if you would be interested. I have a INJEN w/ filter. If you are interested shoot me a pm.
