I am going to be buying a Motordyne Plenum Spacer and was wondering if there is a any difference between the..

5/16" Basic Plenum spacer $199

and

5/16" Iso Thermal plenum spacer $240


Beside the Iso thermal gasket does it do anything else more power or is it just for Heat soak to keep the Plenum cooler?

Help would be great looking into buying one with in the next couple days

Thanks

 

iso..no complaints. Cooler equals more power. Does it make a significant difference? mmm prolly not, but it def can't hurt.

 

ok thanks for the answer

 

Two things I've learned

1. Always do it right, the first time (ie get the iso)
2. Always know what your final goal for your car is, and keep that in the back of your head.

 

Ya kk cool JTrain thanks

 

1+ for both of the answers above.
