Overview:

The Mishimoto Intercooler Kit is a premium performance upgrade designed specifically for 2019 to 2024 Dodge Ram 2500 and Ram 3500 trucks equipped with the 6.7L Cummins engine. This intercooler kit is engineered to enhance your truck’s cooling efficiency, supporting higher boost pressures and improving overall engine performance. Whether you drive a stock or modified Ram, this intercooler provides reliable, consistent cooling to help maintain optimal intake air temperatures under demanding conditions.

Built with durability and performance in mind, the Mishimoto intercooler reduces outlet air temperatures by up to 20°F compared to the factory unit, ensuring your engine runs cooler and more efficiently. Its robust construction and advanced silicone boots make it a dependable choice for Cummins owners looking to maximize power and reliability.

Key Features:

This intercooler kit combines advanced materials and thoughtful engineering to deliver superior performance and durability. Key features include:

• Cast aluminum end tanks for enhanced strength and heat dissipation
• Dense bar-and-plate core design providing 63% larger core volume than stock
• 44.7% less restrictive airflow compared to the factory intercooler for improved boost response

Construction & Design:

The Mishimoto Intercooler Kit features cast aluminum end tanks that provide superior durability and thermal conductivity compared to plastic or stamped steel alternatives. The bar-and-plate core is densely packed to maximize cooling surface area, allowing for efficient heat exchange even under high boost conditions. This design reduces intake air temperatures significantly, which helps prevent heat soak and maintains engine performance during extended heavy-duty use.

Included silicone boots utilize Mishimoto’s proprietary DuraCore™ technology, engineered to withstand extreme temperatures, high boost pressures, and exposure to fuel and oil contaminants. This ensures a secure, leak-free connection that lasts longer than standard silicone couplers.

Performance & Sound

By reducing intake air temperatures by approximately 20°F, this intercooler improves combustion efficiency and power output. The 44.7% reduction in airflow restriction compared to the stock intercooler enhances turbocharger response and throttle feel. While primarily focused on cooling performance, the improved airflow dynamics may also contribute to a smoother engine sound under boost.
