Wehrli 17-19 Chevrolet 6.6L L5P Duramax Passenger Side 3.5in Intercooler Pipe - Gloss White
Improve intercooler performance and add a crisp, clean look to your 2017–2019 Chevrolet Silverado HD or GMC Sierra HD with the Wehrli Custom Fabrication Passenger Side 3.5-inch Intercooler Pipe in Gloss White for the 6.6L L5P Duramax diesel. This aluminum intercooler pipe features a full 3.5-inch bore that delivers cooler, denser charge air to the intake manifold — improving throttle response, lowering EGTs, and supporting higher power levels over the factory plastic tube.
The brilliant Gloss White powder coat gives this pipe a premium appearance that pops against any engine bay background. Wehrli's USA-made intercooler pipes are precision mandrel-bent to exact specifications, ensuring a factory-perfect fit while offering performance that far exceeds the OEM plumbing. Silicone couplers and T-bolt clamps are included for a complete, bolt-on install.
