Wehrli 03-07 Dodge 5.9L Cummins Passenger Side 3in Replacement Intercooler Pipe - Bengal Red

This 3-inch passenger side intercooler pipe from Wehrli Custom Fabrication is made from mandrel-bent aluminum, a strong material that resists corrosion and helps maintain consistent airflow. It's designed specifically for the 2003-2007 Dodge Ram 2500 and 3500 models equipped with the 5.9L Cummins diesel engine, working with both stock and upgraded Holset HE351 turbos that use the factory intercooler.

Aging factory intercooler pipes can develop leaks, especially when you increase boost pressure. This Wehrli pipe addresses that by including high-quality silicone boots and stainless steel T-bolt clamps, which create a solid seal to prevent boost leaks. The smooth, mandrel-bent aluminum construction also helps improve turbo spool-up and throttle response by allowing air to flow more freely to the engine, potentially leading to cooler Exhaust Gas Temperatures (EGTs). It comes finished in a durable Bengal Red powder coat for a custom look.

This pipe is a direct bolt-on replacement for MOPAR part numbers 55056538AC, 55056538AB, 55056560AB, 55056563AB, and 55056565AA. No tuning is required for installation, and it fits stock trucks without needing other modifications. For even better airflow, consider pairing it with Wehrli's high-flow intake horn and the driver's side intercooler pipe.
