---tab Description--- 5.9L/6.7L Cummins Bar-and-Plate Intercooler Overview The 5.9L and 6.7L Cummins engines are legendary for making massive, tire-shredding torque. But pushing high boost and heavy loads through the factory plastic-tank intercooler is a recipe for disaster. Whether you're towing a 20,000 lb gooseneck trailer or running a high-boost compound turbo setup, you need an intercooler built to handle extreme pressure and heat. Enter the SPELAB Heavy-Duty Bar-and-Plate Intercooler. We ditched the weak factory crimped plastic tanks and replaced them with indestructible Cast Aluminum End Tanks, mated to a massive 3.35-inch Bar-and-Plate core. Boasting a 34% larger core volume and massive 3.5-inch inlet/outlets, this competition-grade intercooler dramatically reduces restriction. It acts as a massive thermal sponge, absorbing temperature spikes to drastically lower your Exhaust Gas Temperatures (EGTs) and Intake Air Temperatures (IATs). Upgrade to SPELAB to extend your turbo's life, maximize your tuning potential, and permanently bulletproof your Cummins charge air system.

Factory plastic tanks will explode under this pressure. Our solid cast aluminum end tanks provide unmatched structural integrity and smooth internal airflow, capable of holding 100+ PSI without ballooning or leaking. Massive 3.35" Bar-and-Plate CoreFeaturing a 34% increase in core size over the stock 2.48-inch unit. This heavy-duty bar-and-plate construction provides immense thermal capacity—crucial for preventing heat soak during long, heavy towing grades or intense sled pulling. High-Flow 3.5" Inlet & OutletCummins engines need to breathe. We engineered this intercooler with massive 3.5-inch connections to ensure maximum airflow volume, reducing pressure drop and allowing large single or compound turbo setups to spool faster and hit harder. Drastic EGT ReductionBy delivering a significantly cooler, denser air charge to the intake manifold, this intercooler directly combats the dangerously high EGTs often experienced in tuned or heavy-towing 5.9L and 6.7L trucks. Premium T-Bolt Clamps IncludedTo ensure your connections hold up to extreme Cummins boost, we include premium constant-tension T-bolt clamps for a blowout-proof installation at the intercooler joints.
