I have a 2006 Quad Cab Hemi. I just put a flowmaster Super 40 on it (sounds sweet as hell) and now i am looking to get a cold air intake to mod it even more. However, i odnt know which one to get. I heard that K&N is THE BEST. How about AEM Bruteforce? or AIR RAID? Also, how about the CAI that are sold on ebay for like less than $75? They say that they sell their system with a K&N filter cone along with the tube? Any Suggestions?
