WCFab 3-Inch High Flow Driver Side Intercooler Pipe for 2017-2019 Chevrolet/GMC (6.6L) - Gloss White

Fits select 2017-2019 Chevrolet Silverado and GMC Sierra 2500 HD / 3500 HD (6.6L).

The WCFab 3-inch High Flow Driver Side (Hot Side) Intercooler Pipe addresses a common weak point in the 2017-2019 L5P 6.6L Duramax drivetrain. This kit replaces the restrictive factory two-piece 2.5-inch intercooler pipe with a high-flow, one-piece 3-inch mandrel-bent tube. By increasing the diameter and smoothing the transition, this pipe improves airflow efficiency and turbocharger response.

Engineered for long-term reliability, this kit includes heavy-duty silicone boots designed to withstand higher boost pressures and temperatures than factory components, effectively eliminating the risk of blown boots during heavy towing or high-load conditions. The assembly is finished in a durable Gloss White powder coat for a premium under-hood appearance and installs as a direct bolt-on with no tuning or additional modifications required.
