GM Duramax LB7 - Intercooler Pipe & Boot Kit (2002–2004)

GM Duramax LB7 - Intercooler Pipe & Boot Kit (2002–2004)

Bring new life to your LB7 with this high-flow Intercooler Pipe & Boot Kit. The factory intercooler piping on 2002–2004 Duramax trucks is full of tight bends and restrictive passages—limiting performance and raising EGTs. This kit replaces those weak links with polished 3” aluminum pipes and heavy-duty silicone boots designed to move more air, run cooler, and hold strong under boost.

Key Features:

• Polished 3" Aluminum Piping: Larger diameter with smoother bends for improved airflow and quicker turbo response.

• Heavy-Duty Silicone Couplers: Multi-layer, oil-resistant, and built to handle extreme heat and high boost without cracking or failing.

• Performance Gains: Reduced restriction lowers EGTs and supports horsepower and torque increases—especially on tuned trucks.

• Complete Hardware Kit: Includes all clamps, couplers, and fittings for a secure, leak-free installation.

Restore Flow. Reduce Temps. Boost Power.

This upgrade isn’t just about looks—though the polished finish does add a clean, aggressive touch under the hood. By eliminating airflow bottlenecks and sealing with premium silicone boots, this Intercooler Pipe & Boot Kit delivers sharper throttle response, cooler running temps, and long-term reliability.

Compatibility:

• 2002, 2003, 2004 GMC Sierra 2500HD/3500HD 6.6L Duramax LB7

• 2002, 2003, 2004 Chevy Silverado 2500HD/3500HD 6.6L Duramax LB7
