Fits

If you're looking to clean up your engine bay and finally hear more of that sweet intake noise from your 2004.5-2010 Duramax, the Dirty Resonator Plug is the solution. This simple but effective mod allows you to delete the bulky, plastic factory resonator box on your truck, opening up space for better aesthetics or custom piping.

We believe in parts you can trust, so we’ve precision-machined these plugs from high-quality billet aluminum. Each unit is finished with our Mil-Spec Type II anodizing in our signature color and laser-engraved with the Dirty Diesel Customs logo. Fitted with a high-quality O-ring, this plug provides a tight, reliable seal that handles boost pressure without breaking a sweat.
