After Searching I couldn't find what is better..Either to buy the kinetix intake plenum for 300 or the Plenum spacer for 270? I want the most power 30 dollars not an object. Car has intake and test pipes. Or can you do both?

 

Get the Motordyne 5/16

 

wouldn't it be a better performance gain to get an actual plenum instead of a Gasket lol. Thats what it looks like. I don't know if I get a better gain I'll spend 30 bucks.. I guess what I'm asking is what is better performance gain..An aftermarket plenum or a spacer

 

The Motordyne is more than a gasket. But if you want a chunk of plastic (Kinetix), be my guest.

Either way you go, you don't get that much of an increase though.

 

For the best N/A performance gains, I recommend switching to 3.9's

 

Allright so they're both similar in performance gains.. Thanks
