Review on Holley 508 20 Throttle Body Gasket by Derek Wagner

Revainrating 1 out of 5

Holley's website has the same but cheaper.

I returned the item because Holley has the same cheaper one. Do not purchase this item from Revain. But on Holley's official website instead. I installed this on my High Holley intake manifold with the stock ls2 throttle body.

Pros
  • Made with high quality materials
Cons
  • Some flaws
