Wehrli WCFab Red 3in Driver Side Intercooler Pipe for 2004-2010 Chevrolet/GMC 2500/3500 (6.6L)

Fits select 2004-2010 Chevrolet Silverado and GMC Sierra 2500 HD / 3500 HD (6.6L LLY/LBZ/LMM Duramax).

Upgrade your Duramax's cooling system with the WCFab One-Piece High-Flow 3-inch Driver Side Intercooler Pipe. This component is engineered to replace the restrictive 2.5-inch OEM hot side pipe, significantly increasing airflow for improved turbocharger efficiency and performance. While the factory pipe utilizes a reverse-style bead roll at the turbo—a design prone to blowing off under increased boost—this Wehrli Custom Fabrication pipe uses a superior configuration with high-pressure rated straight boots for maximum reliability.

Each pipe is finished in a durable WCFab Red two-stage powder coating for long-lasting corrosion resistance and a custom under-hood look. The kit is a direct bolt-on solution that eliminates the failure-prone angled boots of the factory setup, ensuring your charge air system remains sealed even under heavy load.
