GM Duramax LB7 - Intercooler Pipe & Boot Kit (2002-2004)
Type: Intercooler Pipe
Restore flow. Reduce temps. Boost power in your LB7 Duramax.
Bring new life to your early LB7 Duramax with this Intercooler Pipe & Boot Kit. The stock 2002β2004 piping is restrictive, with tight bends that choke airflow and raise EGTs. This upgrade replaces weak factory parts with polished 3β aluminum piping and heavy-duty silicone couplers, delivering cooler temps, better throttle response, and reliable boost under pressure.
