Just installed my K&N CAI about two weeks ago. Very easy install, with the exception of a couple screws (I didn't have a very larger extension for my wrench). Definitely gives exhaust a deeper tone compared to stock. Installed a Borla exhaust a few days after and I am loving the performance, sound and added gas mileage. My drive consists of about 60% highway and 40% city, and before these mods it was rare if I cracked 20 mpg. After my first full tank of gas I got 21.5 mpg! Definitely recommend!
