| 2017-2022 | Chevrolet/GMC | Duramax w/ 6.6L |
Eliminate the look of cheap factory plastic and bring some much-needed character to your 6.6L Duramax engine bay. The engine oil fill cap is a focal point of the upper engine, and our billet aluminum dress-up cover is the fastest way to replace that dull OEM finish with a clean, high-performance look.
Designed to integrate seamlessly with your factory hardware, this cover is engineered to press-fit or glue directly onto the original cap. This ensures you maintain the reliable sealing and easy-grip functionality of the OEM unit while completely transforming the visual appeal of your rig. It’s a simple, reliable upgrade that reflects the quality of the parts you run.
