Price: $0.01 Pros: Throaty growl under acceleration, .. other than that? IDK Cons: None so far? Recommended? Yes
Comments: I recieved mine from a family friend. Easy to install.. I have the velocity stack along with the larger cone filter. Everything was straight foward. In terms of power delivery I really don't notice much. ? Gas milage is insane with my XJ.

I chose the smaller filter. I get slightly better mpg and it sounds cool. I swap it out for the factory air box before I do any serious Offroading, for fear it gets splashed.
one other negative thing is it causes your check engine light to come on. so once a year change back to your factory air box, and disconnect the battery for a second, so to reset the comp. and drive about 60mi before getting an inspection.
