thanx

 

???

 

5/16 spacer adds the most hp through rmps ranges i believe or you can just buy the Mrev2 both are the same thing except the Mrev2 is actually the whole half of the manifold.... so you will only have 2 peices vs the spacer makes you manifold 3 peices

 

So I Should Get The 5/16 What Other Mod Compliments This Spacer???

 

what do you mean compliment your spacer?
