Billet polish aluminum oil cap with seal. Get rid of your stock plastic oil cap and replace it with a polished billet aluminum oil cap to shine up your engine bay! This will fit all of the 3800 series II or III engines stock or polished aluminum valve covers. It will also fit Cobalts and Ion Redlines! At this price, you can't go wrong!

COLOR NOTE: The color you select determines the color of the ZZP logo, not the color of the circle. Please choose carefully.

Fits so many models/engines:

This cap fits many makes and models, but under our platforms will fit any W-body or 3800 car, Ecotec vehicles (Cobalt, Ion, HHR, etc). Does not fit LTG vehicles or Sonic/Cruze. To ensure fitment, take your stock oil cap off. If it only has one locating tab on the valve cover and one slot on your oil cap this cap will fit. If your oil cap has two slots you need our V2 version found here.
