hey guys just want to know if buying a cold air intake is work the money or not for extra hp and mpgs
thanks

 

I have a 5.4 FX4 2003 f150 and just put a K&N polished aluminum 77series on my truck and I love it. I can definately tell better mpgs and I ain't been driving it like I'm trying to save mpgs LOL! But in my opinion I think its great. Glad I got one.

 

yeah i was thinking about the 57 or the 77 but i think i will put in the extra cash and get the 77 series.

 

Or save yourself a **** load of money and do Gotts Mod!
