2020+ L5P Duramax Cold-Side Charge Pipe Adapter

Introducing our 2020+ L5P Duramax cold-side charge pipe adapter for Chevrolet Silverado and GMC Sierra HD trucks, designed for high-pressure applications where the factory intercooler connection becomes a weak point. This adapter was built to help prevent boot blow-offs, boost leaks, and power loss when running aftermarket cold-side charge piping. These fit and are for the 3” cold side piping kits. 

From daily-driven HD trucks to heavy towing, sled pull, and performance builds, this billet aluminum adapter provides a rigid, consistent sealing surface that holds up under heat, vibration, and increased boost. The billet construction maintains clamp tension and alignment far better than factory-style connections, especially on tuned 2020+ L5P Duramax platforms.

This version is billet aluminum only and is intended for trucks that see real use and higher cylinder pressure. Installation is direct bolt-on with no cutting or permanent modification required.

Tuning Notice:
This product is intended for off-road or competition use only. Vehicle tuning may be required. Improper calibration or excessive boost can result in engine damage.
