is one better than the other? or does one just cost more? (CAI filter) I have a spectre, was not really impressed.

 

Not having had the spectre I can't say but I've been quite pleased with my K&N.

 

go to stillen.com they have the injen intake i have and it makes a noticeable difference in the sound of the V8 plus a good notice in power and surprisingly enough when i'm being responsible and sensable with it on the highway my 4dr 4wd had about a 5mpg better highway gas mileage! but i rarely see that as i like to hear my girl moan going down the road! (talking about the truck of course)
