Just cause you install an aftermarket part on the truck does not mean that ford will not honor their warranty. Lets say I put a supercharger on the truck and it blew a rod out of the block. Ford will say it was cause of the blower but they have to "PROVE" it was the blower. So you take them to court, they tear down the engine, and low and behold someone forgot to tighten one of the rod end cap bolts... So as long as ford can prove the intake or whatever you're installing caused the problem then and only then will your warranty be void otherwise install all the parts you want! As soon as I get my raptor a whipple is going on after break in and a few oil changes.
