well.. this is a repost from my other Jeep sites... all info in one article.. so let the bash/debate begin...
i NEVER noticed anything from the K&N on my ZJ, so after borrowing one, i just put my stock ZJ box and tubes back on. i never liked the idea of having an open element in the engine bay anyway, but im mainly about performance, and when K&N advertised big gains with their system, i wanted one. i never thought about how they tested them though. on a dyno, with the hood OPEN and a ginourmous fan blolwing at the front of the truck. well...
a lil info about CAIs
and better yet
im not bashing K&N spectre or any other brand, i personally hate all of them and the only thing ill run of K&N are their oil filters for my Impala, Olds, and Saturn.
so what are yalls opinions??
