Chevrolet Silverado Intercooler Pipe – Driver Side – Wehrli – High Flow 3 in – Chevy Orange (2017–2019). A direct-fit hot-side upgrade that replaces factory tubing with a larger 3-inch path.

Built by Wehrli Custom Fabrication (WCFab) for the 6.6L Duramax L5P, this driver-side pipe fits Silverado and Sierra 2500/3500 HD. It replaces the two-piece 2.5-inch OE assembly (GM 87839947) with a single 3-inch high-flow pipe and fewer joints. Premium silicone boots withstand higher pressure and temperature than stock, secured by stainless T-bolt clamps. Finished in Chevy Orange powder coat. Bolt-on for stock trucks; no tuning required.
