I'm waiting for my K&N filter to come in next week but I was wondering just how noticeable your guys' performance/acceleration changes have been after dropping it in? I plan to disconnect the battry to reset the computer after installing it.

 

If it's the drop in panel filter, it's good for about 4-5 hp but it's not noticeable to me. I'm sure it's breathing better and that will help the mpg.
