DESCRIPTION
Product Overview
-
OEM plastic turbo resonators on 2017+ GM 6.6L Duramax L5P engines are prone to heat-soak embrittlement, stress cracking, and unwanted boost/intake leaks over time. Furthermore, the factory plastic chamber acts as an acoustic baffle that silences spool tones and creates unnecessary bulk in the engine compartment.
- Engineered to permanently seal the resonator cavity, this L5P Turbo Resonator Delete Plug replaces the failure-prone factory plastic housing with a CNC-machined billet aluminum seal. It locks out intake air leaks, restores smooth intake tract geometry, and lets your L5P’s natural turbo spool sound shine through while freeing up space under the hood.
Key Features
- CNC-machined high-grade T6-6061 billet aluminum for a strong, precise swap.
- Seals the intake tube cavity so air turbulence disappears and fresh air runs straight into the turbo for snappier throttle response.
- Strips the noise-dampening chamber so the 6.6L L5P lets out a crisp, aggressive, deeply satisfying turbo spool.
- Deletes the oversized OEM plastic resonator box in one shot, opening up engine bay space and simplifying routine maintenance.
FAQ
Q: Should I expect a power gain from this delete plug?
A: Don’t count on a noticeable power bump. The real payoff is cosmetic (a cleaner engine bay), acoustic (the turbo whistle comes back), and protection against vacuum/air leaks from the cheap OEM plastic resonator.
Q: Do I need a tune, and will the Check Engine Light come on with this plug?
A: Neither. It’s a purely mechanical change to the intake ducting ahead of the turbo, so no tuning or programming is needed. It doesn’t touch any engine sensors or emissions systems, meaning no error codes and no warranty concerns.
Q: How does this plug go in, and is any cutting involved?
A: No cutting, no fabrication. It’s an OEM-style snap-fit, so you just loosen the hose clamp, pull the bulky plastic resonator box out, slide the billet plug into the open port on the intake tube, and tighten the factory clamp back down.
Q: What material is this delete plug made from?
A: It’s CNC-machined from high-grade T6-6061 billet aluminum with a durable, corrosion-resistant anodized gold finish, pressure-resistant fit.
