Default Re: sluggish feeling after installing K&N CAI

I's start by puting the old air filter setup in there and see if it makes a difference. The oil on the MAF sensor from those filters has happened to quite a few owners. You may want to get a Superchips programmer (that's the one I use) and see if you can pull codes. FWIW- The programmer really wakes that engine up. ...more than the air intake. If you switch back to the stock setup and still have it, leave the stock setup on while ot goes to the dealer. If you are in warranty, they will tell you it's teh oiled filter's fault and that MAF sensor isn;t cheap.

From your description, I've always felt that way about all of my past H2's. Maybe you're jsut noticing it more since you are hearing more of the intake/ engine sound. That's why I put the programmer on, you can firm up the shift pointsm raise the rev limiter, and improve driveability.

Outside of that, that's about all I can add for now. If you get the programmer and can pull a DTC, I can help a little more.
