Optimize your Peterbilt 378’s cooling and air intake systems with the Kustom Truck Radiator and Charge Air Cooler Piping Kit, designed specifically for 2004–2007 models installing a Caterpillar 3406E or C15 single turbo engine. Crafted from high-quality 304 stainless steel, this kit includes four durable tubes—right and left side charge air cooler (CAC) tubes, upper and lower radiator tubes—available in either a mill or polished finish for enhanced durability and a customizable aesthetic. The right side CAC tube is configured for a 4" 90-degree turbo outlet elbow (Kustom Truck PN: 99999040 or similar), while the left side CAC tube pairs with a 45-degree intake elbow clocked for an upward and forward-facing inlet (Kustom Truck PN: 99107003 or similar). The upper radiator tube is designed for a vertical-facing thermostat housing outlet, and the lower radiator tube accommodates a 3" water pump outlet. Ideal for mechanics and fleet owners performing engine conversions or system upgrades, this kit delivers precise fitment for Peterbilt 378 trucks. Note: Specify mill or polished finish when ordering. Confirm compatibility with your specific turbo elbow, intake elbow, thermostat housing, water pump, and chassis configuration by contacting Kustom Truck for fitment verification.
