2000 F350-F250 7.3 liter diesel homemade air intake modification, cold air intake 6637 Napa air filter mod

6637 Air Filter Mod

I researched and priced a lot of aftermarket high flow cold air intake filter systems before I decided to just

 build my own. I was not going to pay $350 + for something I could build myself and build like I

wanted it. I used a simple cardboard template and did a LOT of measuring and cutting till I got the 

perfect fit for the under hood contours. The rubber trim is made from an extra cowl to hood seal. I

modified the battery tray so I could move the battery forward to allow plenty of room for the

massive Napa 6637 air filter. This large filter, combined with a ram air modified version of the "zoo dad" mod

and the fender air inlet, gives the 7.3 liter all the air it needs.
