Wehrli 2020+ Chevrolet 6.6L L5P Duramax Driver Side 3in Intercooler Pipe - WCFab Red
Maximize the performance of your 2020+ Chevrolet Silverado HD or GMC Sierra HD with the Wehrli Custom Fabrication Driver Side 3-inch Intercooler Pipe in WCFab Red for the 6.6L L5P Duramax diesel. Built to replace the factory plastic intercooler pipe with a robust, mandrel-bent aluminum upgrade, this pipe reduces charge air temps and improves turbo spool for a noticeably more responsive diesel.
Wehrli's signature WCFab Red powder coat is bold, heat-resistant, and built to last — giving your engine bay a distinctive performance appearance while standing up to the rigors of daily driving, towing, and off-road use. Every Wehrli intercooler pipe is made in the USA to exacting tolerances, ensuring a direct bolt-on fit with zero modifications needed.
