Which is better, or is it all preferance?

 

if you go by #'s, then i believe the MD one performed the best in the shootout.

 

MD has gained the respect of this forum with solid gains and superb customer service. Roll with MD.

either... =]

 

+1

 

MD ftw!

+400 for the Motordyne

 

Lol, i think the MD wins this one. Aight I am going to look for one.... Now for pulleys haha.

 

Absolutely!

The MD spacer and iso-thermal lower collector together represent the most intelligent pennies I've ever spent on any car I've ever had. And it's not just about peak hp gains, but better engine manners and a broader power band as well.

And the sound is amazing.

 

FOr install, did you guys have to remove teh struct bar?

 

im planning on picking up the 5/16th iso-thermal and MREV2 pretty soon.

 

Yes, but you can put it back on afterwards (with the 5/16th spacer).

I would direct new members to the Sport-Z magazine Plenum vs Plenum Spacer Shot-Out. But you have reviewed the results of course.

 

Is there a link or something? I remember reading it before, but I don't remember where it was now and I have company. If not, I'll search later and bookmark it for future reference.

 

Crawford plenum! for the price

 

I've had both the MD and AAM spacer...I stayed w/ the AAM spacer b/c I like their design. Plus they have lots of other components for the Z.

 

yah... i am totally imparcial here......a lot more poeple ahve the MD spacer, when it all started with the Intense group buy and it just took off even more after that... i have motordyne...but i have seen the aam as well and i like it too... thats why i said either...
