Product Description

The BD DIESEL 1045170 Iron Horn Turbo Kit is a clean, drop-in turbo upgrade for 2003–2007 Dodge Ram 2500/3500 trucks equipped with the 5.9L Cummins. This kit is built for drivers who want more power, quicker response, and lower EGTs while maintaining factory-style drivability and a straightforward installation. Featuring an S361SXE/76 turbocharger with a 0.91 A/R exhaust housing and a BD high-flow 2-piece pulse T4 manifold, the Iron Horn delivers a major airflow and reliability upgrade over the aging factory turbo and manifold.

Designed as an easy “no extra piping” upgrade, this kit replaces the factory turbo and manifold with a modern, efficient S300 SX-E based unit. The result is improved boost response, reduced drive pressure, and a strong foundation for towing or street performance builds. The turbo is rated at approximately 77 lb/min airflow and is commonly paired with supporting fueling and tuning for power levels around 500HP potential depending on overall truck configuration.
