Has anyone done a diy ram air on a 5.4 or 4.6? I searched but didnt find much.

 

Do a search for the Gotts mod.

 

what I did with a F250 and my current f150 was get volant cold air intake which has ram air capability on certain vehicles. I strongly recommend VOLANT. it's the only TRUE cold air intake. I have the 4.6 and I love it on mine. if you had a 5.4 you could get the ram air addition. I'll give you the url:

5.4 is http://www.volant.com/idetail.asp?ID=52

4.6 is http://www.volant.com/idetail.asp?ID=53

ram for 5.4 is http://www.volant.com/pdetail.asp?ID=173
