aFe BladeRunner GT Intercooler

2013–2018 RAM 2500/3500 6.7L Cummins

Part #: 46-20132-B

Overview

The aFe BladeRunner GT Intercooler with tubes is a high-performance upgrade designed specifically for 2013 to 2018 RAM 2500 and 3500 trucks equipped with the 6.7L Cummins engine. Engineered to replace the factory intercooler, this advanced intercooler system delivers superior cooling efficiency and airflow, making it ideal for enthusiasts and professionals seeking enhanced engine performance and reliability under high boost conditions.

By utilizing a robust bar and plate core design, the BladeRunner GT intercooler significantly outperforms traditional OE tube and fin cores. This results in cooler intake air temperatures, improved combustion efficiency, and reduced exhaust gas temperatures, which collectively contribute to better power output and engine longevity.

Key Features

The BladeRunner GT intercooler incorporates cutting-edge technology and thoughtful engineering to maximize performance and durability. Key features include:

• 3-inch bar and plate core design for superior heat dissipation and airflow compared to OE tube and fin cores
• Heavy-duty 3/16-inch TIG welded aluminum plate end tanks for strength and durability
• Three multi-directional internal vanes in the end tanks to efficiently direct airflow through the entire core
• Four 1/8-inch pre-tapped ports for easy installation of gauges or auxiliary inputs
• Pressure tested to 200 psi, suitable for high boost and demanding applications
• Proven to reduce intake air temperatures by up to 200 degrees and exhaust gas temperatures by 100 degrees
• Increases airflow by approximately 30%, enhancing engine breathing and performance

Construction & Design

The BladeRunner GT intercooler is built with premium materials and precision craftsmanship. The core features a robust 3-inch bar and plate design, which excels at dissipating heat more effectively than conventional tube and fin cores. The end tanks are fabricated from thick 3/16-inch aluminum plates, TIG welded to ensure a leak-free, durable assembly capable of withstanding high boost pressures.

Inside the end tanks, three multi-directional vanes optimize airflow distribution, ensuring that air passes evenly through the entire core surface for maximum cooling efficiency. This thoughtful design reduces hotspots and maintains consistent intake air temperatures, even under demanding conditions.

Performance & Sound

Tested extensively under real-world conditions, the BladeRunner GT intercooler delivers measurable performance improvements. It achieves a remarkable 200-degree drop in intake air temperature and a 100-degree reduction in exhaust gas temperature, which helps protect the engine and improve combustion efficiency. The increased airflow capacity by 30% supports higher boost levels and power gains without compromising reliability.

Installation & Fitment

This intercooler is a direct fit replacement for 2013–2018 RAM 2500 and 3500 trucks with the 6.7L Cummins engine. Installation requires no major modifications, making it a straightforward upgrade for experienced DIYers or professional installers.
