Due to the difference in opinions I have heard on these items. I thought id ask a more useful source and not those who just want you to buy their parts. again im still learning 4.6 motors ive came from chevys so no heat on this question. But will these be useful mods on a 99MGM?

-Ported Upper Intake Plenum

-70 or 75mm Throttle Body

somewhat... If you really want a gain, put on some PI heads + intake and call it a day

PI intake and Heads FTW. Upper Ported Plenum is decent too... along with an marauder MAF, zip tube and tune, i bet you could pick up a good 30rwhp or more...

Once you get the PI heads and intake, go with the Aviator 70mm throttle body. It is the same as the FRPP throttle body for a lot less $$. PM me if you are interested I can send you a link to somebody that sells them. He is not a vendor here so I don't really want to post it.
