WCFab 3in Driver Side High Flow Intercooler Pipe for 2017-2019 Chevrolet/GMC 2500/3500 HD (6.6L) - Gloss Black - WCF100708-GB

Fits select 2017-2019 Chevrolet Silverado and GMC Sierra 2500 HD / 3500 HD trucks equipped with the 6.6L L5P Duramax diesel engine.

Upgrade the restrictive factory charge air system with the Wehrli Custom Fab (WCFab) 3-inch High Flow Driver (Hot) Side Intercooler Pipe. This one-piece mandrel-bent 3-inch pipe replaces the restrictive two-piece 2.5-inch factory assembly, significantly improving airflow from the turbocharger to the intercooler. By eliminating the factory seams and joints, this kit reduces potential leak points and enhances turbo response.

Designed for maximum durability under high boost conditions, this kit includes heavy-duty silicone boots engineered to withstand higher temperatures and pressures than OEM components. The system installs as a direct bolt-on replacement with no tuning required and is finished in a durable gloss black powder coat for a clean, professional look under the hood.
