I read about another guy who used a 70mm throttle body off of an 5.4 f150. So, I decided to give it a try. I ordered one off a 2002 5.4 truck for $25.00. I installed it tonight and It works great. Throttle respons seems crisp and the car feels alot better. I installed a k&n fipk at the same time so it was a combined effort. This is a great mod and it only cost me 25 bucks and a little time.

 

Hmmmmmm interesting!!

 

stock f150 size isnt 70mm i dont think i need to go look at my old one in my garage.
