Anyone have a issues with there k and n drop in filter?I went and bought one and put it in and after i let the truck warm up,I went for a spin and floor it.Durning the 1st to 2nd the is a loud hissing sound,sounds like it stuggles then gets going in second.i think it stumbles and i can feel it in the rear end.I dont think i scratch 2nd but maybe i do.ohh well. 05 5.4l 2wd.It ****s at 5100 rpms in fisrts then goes down to like 2k and then goes.Any ideas?or thoughts?
Does that happen with a intake?thanks

 

after debating on getting a CAI i decided that the HP gains weren't worth the $ and possible problems. That said i just put in a k&n drop in week ago. I was amazed at the difference. After 3 fill-ups im getting inbetween 1.5-3 MPG better and i can now spin my tires for about 6-8 feet. My only suggestion would be to reset the PCM. I didn't do this but im not having the problems you are either.

 

 

Odd. Not sure the K&N dropin and that issue you have would be related?

Reset the PCM for sure.

 

I've been re-thinking buy a cold air intake and just going for the K&N drop in..how much did it run you?

 

Its was $45 bucks at autozone.How do i reset my pcm?Is it just disconnecting the battery and waiting?I know that was how it was done with my Evo.Thanks

 

No problems with my K&N drop in.

 

Yep. Disconnect and wait for about 10 min.

 

I have never had a problem with my K & N drop in! did have a problem with the air seal on the filter holder, it just went bad and ripped off. Maybe from the repeated opening to clean.

 

No problems here. . . sounds like its not sealing correctly.

 

No problems here either. $34 from Wal-mart.

 

Just a thought, were you low on gas when you did this? Mine acts the same way when I am low on gas and I punch it.
