Wehrli’s passenger-side 3.5" intercooler pipe for 2020–2025 Chevrolet 6.6L L5P Duramax replaces the restrictive factory plastic two-piece with a one-piece 14‑ga. aluminum pipe to improve flow and reduce boost leaks. It uses a CNC‑machined flange with double O‑rings and an upgraded silicone boot with a black anodized billet adapter to withstand higher boost pressures. Includes threaded bung for the OEM intake temperature sensor, stainless steel T‑bolt clamps and a powder coat finish. Fits stock trucks as a bolt‑on with no tuning required.
