Does it make a difference between the AAM and Motordyne plenum spacers that one is angled and the other isn't? I know the AAM improves flow in the front of the plenum, but the rear is unchanged. Which spacer will give more performance?

i wouldn't worry about which makes more power.. IMHO.. too small to worry about..

what do you want to do? Correct the inbalanced from two cyliders?? or space them all out?? which makes more sense to you?


This is like the Intake debate.. just pick one and run for the hills...

yeap the only issues with choice is if u have the 300hp engine

the 300hp has a different lower plenum which sorts the air flow issue to the front cylinders somewhat, and fitting the AAM with an angle could upset the balance again. A constant width like the ME would be best....imo

personally on the 03 id go AAM because the angle does work in balancing the airflow
