Wehrli 17-19 Chevrolet 6.6L L5P Duramax Passenger Side 3.5in Intercooler Pipe - Bengal Blue
Add performance and a splash of unique color to your 2017–2019 Chevrolet Silverado HD or GMC Sierra HD with the Wehrli Custom Fabrication Passenger Side 3.5-inch Intercooler Pipe in Bengal Blue for the 6.6L L5P Duramax. This mandrel-bent aluminum intercooler pipe replaces the factory plastic passenger-side tube with a larger 3.5-inch bore, delivering cooler, denser charge air to the intake manifold for improved power output, lower EGTs, and better turbo efficiency.
Bengal Blue is one of Wehrli's most distinctive powder coat colors — a rich, deep blue finish that stands out in any engine bay. The coating is high-temp rated and chip-resistant, designed to survive the rigors of daily diesel use. Includes premium silicone couplers and T-bolt clamps for a fast, boost-leak-free installation.
