These Covers are designed to fit LS2, LS3, and L99 engines with the stock GM returnless fuel rails. They are available in 16ga mirror polished stainless steel or paintable 16 ga mild steel. They are the perfect compliment to upgraded valve covers and help to dress up the stock rails while hiding the ugly wiring harness and injectors. The result is a very clean yet not overdone look that just works with the LS engines. They are easily customizeable by adding graphics, small emblems, custom paint, pinstriping, etc... Each kit includes both left and right covers, with stainless button head bolts and mounting hardware.
