Engineered to replace the factory intercooler, this advanced intercooler delivers superior cooling efficiency and airflow, making it an essential component for diesel enthusiasts seeking improved power and reliability under high boost conditions. Whether you’re towing heavy loads or pushing your truck’s performance limits, the BladeRunner GT ensures your engine stays cooler and runs more efficiently.

Built to handle demanding applications, this intercooler is ideal for those who want to maximize their Cummins engine’s potential without compromising durability or fitment. It offers a significant upgrade over the stock tube and fin core design, providing enhanced thermal management and airflow for better combustion and reduced exhaust gas temperatures.

Key Features

The BladeRunner GT Intercooler incorporates cutting-edge technology and robust construction to deliver outstanding performance benefits:

• 3-inch bar and plate core design that outperforms traditional tube and fin cores
• 3/16-inch thick TIG welded aluminum plate end tanks for superior strength and durability
• Three multi-directional internal vanes in the end tanks to optimize airflow distribution across the entire core
• Four 1/8-inch pre-tapped ports for easy installation of gauges or auxiliary inputs
• Tested to withstand pressures up to 200 psi, suitable for high boost applications
• Proven to reduce intake air temperatures by up to 200 degrees Fahrenheit
• Demonstrated exhaust gas temperature (EGT) drop of 100 degrees Fahrenheit for improved engine longevity
• Increases airflow by approximately 30%, enhancing engine breathing and performance

Construction & Design

The BladeRunner GT Intercooler is meticulously engineered using premium materials and advanced manufacturing techniques. Its core features a robust 3-inch bar and plate design, which provides greater surface area and improved heat dissipation compared to conventional tube and fin intercoolers. The end tanks are fabricated from thick 3/16-inch aluminum plates, TIG welded for maximum strength and leak resistance.

Inside the end tanks, three multi-directional vanes are strategically positioned to direct airflow evenly through the core, ensuring consistent cooling across the entire intercooler. This design minimizes hotspots and maximizes thermal efficiency, which is critical for maintaining optimal intake air temperatures during heavy-duty or high-performance use.

Performance & Sound

The BladeRunner GT Intercooler significantly enhances engine performance by delivering cooler, denser air to the combustion chamber. This results in improved combustion efficiency, increased power output, and reduced exhaust gas temperatures, which helps protect vital engine components under high load. The intercooler’s superior airflow characteristics also contribute to smoother turbo response and more consistent boost pressure.

Installation & Fitment

Designed as a direct-fit replacement for the factory intercooler on 2013–2018 RAM 2500 and 3500 trucks with the 6.7L Cummins engine, the BladeRunner GT installs with minimal modifications. It utilizes existing mounting points and hardware, allowing for a straightforward installation process. The pre-tapped ports simplify the addition of gauges or sensors without the need for custom fittings.
