70mm BBK Throttle body 4.7
 

Have one of these on my truck, yes it rocks got it for a song, My question being would it benefit me to put an aftermarket Mass air flow sensor (does the 02 dakota 4.7 have one), or change out the IAC which is new as well, or would it be better to change out the MAP sensor, are these parts available as a higher performance edition?? The thing sucks ALOT of air thru the cold air intake, lookin to put it to good use... yes u can hear u sounds cool lol

The Dakota uses a MAP sensor. It just senses barometric pressure. I've never heard of a higher performance edition but they can get "sluggish" with age.

thanks for the info havent replaced that yet but have heard it can affect our mileage
