Add a subtle accent to your engine bay with our chrome, beryllium and brushed aluminum oil caps. Unlike competitors products, these caps are made exclusively for Bimmian.com from a solid single piece of aluminum, crafted using the latest billet technology. This single piece approach prevents leaks, maintaining oil pressure as per the OEM cap, while simultaneously preventing oil leakage through the multiple parts of the cap. All our oil caps are machined out of aluminum for perfect fitment. Our silver caps are brushed, and our beryllium caps are anodized with a matte finish. Our chromed oil cap has a fully chromed body over semi-fine machined aluminum. For a great match, make sure you check out our other products available in the same finishes by clicking below. .
