(shown on the Cobalt for Illustration) Jazz up your engine bay with a MPx oil cap, or get one if you have one of our powder coated valve covers to have a matching set.

We at Modern Performance were tired of using universal oil caps on our Chevy Cobalt project cars. So, we designed a new oil cap from scratch that fit nicely into our hands (to make it easier to take it off and on) and is a quality piece. We wanted something that was designed directly off the stock oil cap thread designs so that they would fit snugly and seal well. Here you have it. American made, CNC machined aluminum oil caps, with rubber 0 ring seals, available in polished, blue and red. The blue and red oil caps are powder coated for durability, and so that they will match our valve covers perfectly as well.
