Optimize your engine swap with the Kustom Truck Air Intake Adapter Kit, designed for Peterbilt 386 trucks with a firewall-mounted air cleaner, connecting to the 5" turbo inlet of a Caterpillar C12 single turbo, Cummins ISX CM570, or Detroit Diesel Series 60 DDEC3, DDEC4, or DDEC5 engine. This kit reduces the 6" diameter intake from the air cleaner to the 5" turbo inlet using a specialized elbow. It includes a 6" short-radius 90-degree elbow, a 6" x 5" short-radius 90-degree elbow reducer, 22- and 45-degree elbows, three 6" diameter aluminum tubes, and stainless hose clamps for secure installation. Ideal for mechanics and fleet operators, this kit ensures efficient airflow and reliable performance for custom engine swaps.
