Spacer is available at importpartspro.com

 

Motordyne has both a .25 and .5 inch spacers. It is also cheaper than the other site. If you have a MREV2 this is a perfect match. So going forward if anyone wants to know if you need "anything else" for their injector upgrade (06'07' coupe) the answer is painfully, YES!!!!!

I didn't have to use a spacer with my old injectors and Cosworth rails. Injectors were Power enterprise 510ccs. It's going to depend on the injectors, Deatschwerks or however you spell it are generally the stock height injectors on the smaller ones.
