Industrial Injection 04.5-07 5.9L Cummins 63mm HE351 XR1 Series Turbocharger

The 63mm compressor wheel on this Industrial Injection HE351 XR1 turbocharger is a key feature for those looking to improve airflow on their 2004.5-2007 5.9L Cummins engine. This turbo is built around the popular HE351 platform, but with significant updates to help it perform better. It's designed to provide a noticeable increase in boost and power over the stock unit, making it a solid choice for owners who want more out of their truck without going to an extreme setup.

Industrial Injection has updated this turbo with their XR1 series modifications. This includes a custom-machined compressor cover and a balanced rotating assembly, which helps ensure smooth operation and longevity. The larger 63mm compressor wheel means it can move more air, allowing your engine to breathe easier and make more power, especially at higher RPMs. While it's a direct bolt-on replacement for the factory HE351, you'll want to ensure your fuel system and exhaust can keep up to take full advantage of the improved airflow. It's a well-built unit that many Cummins owners turn to when they want a reliable performance upgrade.

Keep in mind that this turbocharger is not CARB approved and cannot be shipped to California. For optimal performance and to ensure the longevity of the turbo and your engine, it's always a good idea to consult with a professional or refer to the manufacturer's installation guidelines. Proper tuning after installation is also highly recommended to maximize the benefits of this upgraded turbocharger.
