plenum spacer question
hey guys, i'm just wondering what you think of the AAM plenum spacer? i'm thinking about getting one, but there's a couple on the market and i've done the research, both here and other related forums, so i'm just gonna ask straight up, what do you think is better and why? your help would be really good. thanks

The "usual" Motordyne spacer is 5/16" which allows the stock strutbar to work with no problem.
I have the AAM spacer, it will require you to put washers (provided) under the strut bar to raise it so the plenum fits under it.

This is old, but now there is no reason not to go MD. Everything is easier about the install with no chance of rubbing the strut tower.

well, personally speaking - when I install the plenum spacer - i have to adjust the strutbar from the adjustment bolts n the left side of the strutbar - did you do this in your initial review?

More so when the car was hot, the A/C was on and when turning left. I was at the limit for hood clearance at that point and accepted the fact that build tolerances vary from car-to-car and I had one of those cars. This is an unlivable circumstance which can be resolved a number of ways, mine being the decision to use the ME unit which maintains a large amount of clearance on the first try with zero vibration tinkering.

They are good to go with FI.
If FI adds 50% more HP to your engine, you can expect to see approximatly 50% more gains from a plenum spacer.
So far the MD plenums spacers are being used at up to 22 PSI boost @ 700+ HP.
