hey guys !

Is there a really difference between the plenum spacers : Motordyne, AAM, Stunk, etc... No Cosworth cause it's not a spacer...

I know on the Motordyne you can add somes + : copper versions, ceramid gasket, etc...
But concerning the performances ?

 

I herd some people complaining about leaks with the skunk

 

Not sure what the performance differences are if any, but most here use/ recommend MD - myself included. And their customer service rocks~

 

The subject is about 2 years old. Check the Sport Z magazine plenum vs plenum spacer shoot out.

 

Subject has been beaten to death. There is plenty of dyno proof for performance gain of spacers in the intake/exhaust forum. And if you want the condensed version, check the top 100 questions thread.
