Upgrade your Peterbilt 379 Long Hood’s cooling and air intake system with the Kustom Truck Radiator and Charge Air Cooler (CAC) Tube Kit, meticulously designed for 2004-2007 Peterbilt 379 trucks equipped with a Caterpillar C15 ACERT twin-turbo engine from the factory. Available in your choice of mill or polished finish, this kit is crafted from premium 304 stainless steel for exceptional durability, corrosion resistance, and a refined aesthetic. The kit includes a Right Side CAC Tube, Left Side CAC Tube, Upper Radiator Tube, and a two-piece Lower Radiator Tube, all engineered for precise fitment and optimal performance in heavy-duty applications. The Right Side CAC Tube is configured for a 4" 90-degree turbo outlet elbow (compatible with OEM Caterpillar PN: 222-2895 or similar), while the Left Side CAC Tube is designed for a 45-degree intake elbow with an upward and forward-facing inlet (compatible with Kustom Truck PN: 99107003 or similar). The Upper Radiator Tube accommodates a vertical-facing thermostat housing outlet, and the two-piece Lower Radiator Tube is tailored for a 3" water pump outlet. Ideal for owner-operators and fleet managers seeking reliable cooling and air delivery for their Caterpillar C15 ACERT-powered Peterbilt 379, this kit enhances heat dissipation and airflow. Note: This kit is exclusively for 2004-2007 Peterbilt 379 Long Hood trucks originally equipped with a Caterpillar engine and will not fit trucks with a Cummins CM870 ISX due to engine placement differences. Confirm compatibility with your specific truck configuration by contacting Kustom Truck for fitment verification. Enhance your cooling system with this precision-engineered tube kit, crafted for durability, performance, and style.
