Check out the new VMS Racing billet aluminum resonator (Helmholtz Chamber) box delete plug for the 2004.5-2010 Duramax Diesel engines. This plug comes with a VITON o-ring which is the longest lasting, best sealing seal in the industry!
VMS Racing comes back to the rescue to help you add that last finishing touch to your engine bay, and get a little additional whine from your turbocharger with the NEW Duramax resonator box delete plug! When you want more turbocharger whistle and noise coming from your engine bay you need to delete the Helmholtz Resonator Chamber Box that is on your intake piping. You can go out and buy some cheap hardware store plug and do this, but it will look like crap and you will spend an afternoon finding a plug that will fit. This plug replaces the resonator chamber box with a precision CNC machined, VITON o-ringed T6061 billet aluminum cap that not only looks great but functions too.
• Vitton seal.
• CNC machined from a solid piece of T6061 billet aluminum.
• Hard anodized.
• Easy to install.
