I have an 04 F150 and visit the forums. Alot of guys have tried the Air Raid and the only negative I hear is that it is VERY loud. It seems that the K&N is a better value with more horsepower. Also I contacted K&N about the new Typhoon (metal tube) for exchange with my plastic one. They replied that it was not interchangable with the plastic and the horsepower for the Typhoon is alot less than the Air Charger (plastic).
