Does any one have a mac CAI, I have an 04 FX4 w/5.4. Was also wondering if you have to get a tune after you add this

 

I have never used one, but I do sell a lot of them for ford rangers. From what i have heard, their quality is pretty good, especially considering the price. You shouldnt need a tune for it, but I havent tested it, so i cant say for sure.

 

Hey thanks for the help. My brother in law can get me a really good deal on one, but I personaly like the K&N (FIPK). Dont know what to do?
