The OEM plastic end tanks become brittle and are notorious for cracking under pressure, causing massive boost leaks, loss of power, and dangerously high Exhaust Gas Temperatures (EGTs).\u003c\/p\u003e\n\u003cp\u003eRestore and upgrade your classic Duramax with the SPELAB Heavy-Duty Bar-and-Plate Intercooler.

Crucially for the heat-prone LLY engines, this optimized core density delivers maximum charge-air cooling without starving your radiator of ambient airflow. Whether you are towing heavy, running upgraded tunes, or simply bulletproofing your high-mileage truck, this intercooler is built to handle 100+ PSI and last a lifetime.\u003c\/p\u003e\n\u003ch2\u003eBar-and-Plate Intercooler Fitment\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e2001 Chevrolet\/GMC Sierra 2500HD 3500HD LB7 6.6L Duramax\u003c\/li\u003e\n\u003cli\u003e2002 Chevrolet\/GMC Sierra 2500HD 3500HD LB7 6.6L Duramax\u003c\/li\u003e\n\u003cli\u003e2003 Chevrolet\/GMC Sierra 2500HD 3500HD LB7 6.6L Duramax\u003c\/li\u003e\n\u003cli\u003e2004 Chevrolet\/GMC Sierra 2500HD 3500HD LB7 6.6L Duramax\u003c\/li\u003e\n\u003cli\u003e2004.5 Chevrolet\/GMC Sierra 2500HD 3500HD LLY 6.6L Duramax\u003c\/li\u003e\n\u003cli\u003e2005 Chevrolet\/GMC Sierra 2500HD 3500HD LLY 6.6L Duramax\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eHeavy-Duty Intercooler Key Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eIndestructible Cast Aluminum End Tanks\u003c\/strong\u003e\u003cbr\u003eStop trusting 20-year-old plastic.
