Anyone know of a supercharger for a 2003 lincoln aviator?

 

Low sales plus a buyer base that doesn't tend to modify vehicles means you're likely on your own...

I would think that a blower for a Mustang Mach 1 (same basic engine I believe) should work in theory, but underhood fitment is an unknown.

 

Trilogy has an Eaton kit that seems to work great on Mercury Marauders which have the same 32V engine, but I recall seeing that adapting it to an Aviator would be a tough go.

You might check mercurymarauder.net for peformance ideas... I'm not sure how many would work on the Lincoln but it seems worth a shot.
