Single Turbo Conversion Kit for Peterbilt C-15 ACERT Engines (Model Years 2004.5 to 2007)

If you’re looking to ditch the factory twin turbo setup on your 2004.5–2007 CAT C15 Acert, the PDI Single Turbo Conversion Kit is one of the best upgrades you can make for performance, reliability, and easier maintenance.

This complete conversion package replaces the complex factory system with PDI’s proven Big Boss single turbo setup, giving your engine better airflow, improved efficiency, stronger pulling power, and simplified turbo plumbing. Fewer components also means less maintenance and fewer failure points, making this a popular upgrade for working trucks that need dependable performance.

The kit includes everything needed to properly convert your engine to a PDI Big Boss single turbo configuration, including the turbo, manifold, install kit, conversion components, and exhaust downpipe.

When installed together, these components help improve horsepower, torque, fuel efficiency, and overall drivability, giving your C15 Acert the performance it should’ve had from the factory.
