as far as maf's go, get a 02-04 mustang gt maf....you WILL need an ecu tune for it tho..

the lincoln aviator throttle body from ford is under 100 bucks and its a 70mm, witch is a 5mm upgrade from stock, so if you want a bigger tb for real cheap, thats an option, but ya, porting the stock plenum works

i concur with the gt maf, the lightning maf is more for boosted applications...gt maf fits better with a naturally aspirated 4.6
