Hello I am thinking about a cold air intake system for my truck. It is the 4.7 ltr.
If i do this what other up-grades and will i have to adjust the MAS or do a CMOD diagnostic test?
Which is the best system for me to up-grade to without sacraficing fuel millage.
I tow a boat approx 2000lbs plus fuel and gear.

 

I don't think that this can happen.

 

I worked with a Fuzzy, is your name Ken? Thanks, Don
