WCFab Wehrli Custom Fabrication 3" Driver Side High Flow Intercooler Pipe for 2004-2010 Chevrolet/GMC (6.6L) - Gloss Black

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

Upgrade your charging system with the Wehrli Custom Fabrication (WCFab) 3" High Flow Driver Side Intercooler Pipe. This one-piece mandrel-bent pipe replaces the restrictive 2.5" OEM hot-side plumbing with a full 3" diameter for improved airflow and reliability. The factory pipe utilizes a reverse-style bead roll design at the turbo connection that is prone to blowing off under higher-than-stock boost levels; WCFab eliminates this failure point by using high-pressure rated straight silicone boots and heavy-duty clamps.

Finished in a durable single-stage Gloss Black powder coating, this kit provides a professional look while ensuring your LLY, LBZ, or LMM engine maintains consistent boost pressure during heavy towing or performance driving.
