i went the cheap route and got the 3/8 powerlabs plenum spacer... hope its worth it since i cant find a 3/8 motordyne anywhere

 

Cool, let us know how you like it. I just got my Motordyne 5/16 spacer today. I'm going to install it tommorrow along with an oil catch can. Can't wait to see what it does for my coupe.

 

Let's hope you get all the parts required for this install plus all the information.
It's never smart to go cheap when your dealing with a high quality intake
like ours. You couldn't find a 3/8" MotorDyne spacer because they don't make
one....either 5/16" or 1/2". MotorDyne discovered Nissan's design flaw and came up with a solution years ago. They're the best in there field, using
anyone else's not advised....G/L!
