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 known for its tight bends and restrictive flow—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 better turbo response.
- Silicone Couplers: Multi-layered, oil-resistant, and built to handle extreme heat and high boost pressure without cracking or failing.
- Increased Performance: Reduced restriction helps lower EGTs and supports better horsepower and torque gains—especially on tuned trucks.
- Complete Hardware Kit: Comes with everything needed for installation—no additional parts required.
Restore Flow. Reduce Temps. Boost Power.
This upgrade is about more than just looks—though the polished finish does add a clean, aggressive touch under the hood. By removing airflow bottlenecks and sealing with quality silicone boots, this Intercooler Pipe & Boot Kit delivers noticeable gains in throttle response, cooler running temps, and long-term reliability.
