So I havent been a member long on TT and I have searched through many didnt threads, but I was wondering what would be the best CAI for my 2010 Titan crew cab 4x4. It is a flex fuel I seen where some people were saying that it being FFV that could play a factor in which CAI to purchase. Dont necessarily wanna lose gas mileage but I dont mind the noise of it and want what preforms best. thanks everybody!
