Kit came with everything needed to install the phenolic spacers. I bought these in order for wrx top feed fuel rails to clear the avcs on my 04 Sti engine. After a quick cruise around the neighborhood the intake manifold felt warm but not hot at all.

Not sure if they add any more power or not but they helped with some FMIC fitment issues, sealed up my boost leaks, and the bolts that come with it are way better than stock. Definitely putting a set of these on all my future EJ motors
