Wehrli 3.5" high-flow intercooler outlet elbow for 2006–2010 Duramax LBZ/LMM diesels, replacing the factory plastic piece with 14‑gauge aluminum. It uses a CNC-machined flange with double O‑rings, a new wire clip ring, and an upgraded silicone reducer boot with stainless t‑bolt clamps to withstand higher boost pressures. Finished in custom powder coat, it improves reliability and eliminates boost-leak points common to stock parts.
