HKS I/C R-type CT9A EVO9

The HKS R-type intercooler for the CT9A Lancer Evolution IX features a core with a 60mm thick, high-efficiency design. This substantial core size is crucial for dissipating the heat generated by boosted air, which is essential for maintaining consistent engine performance and power output, especially under demanding conditions. The R-type designation signifies its focus on maximizing cooling capacity for performance-oriented builds.

Constructed with HKS's signature attention to detail, this intercooler utilizes a well-built core and end tanks designed to handle increased boost pressures and airflow. The larger core dimensions and optimized internal fin design work together to lower intake air temperatures more effectively than stock or smaller aftermarket units. This improved cooling directly translates to denser air entering the engine, allowing for more efficient combustion and potentially more power. The kit is engineered to fit the specific chassis, minimizing installation complexity for a performance upgrade.

This intercooler is a significant upgrade for Evolution IX owners looking to push their turbocharged engine further. It's designed to work with the factory turbocharger or many common aftermarket turbo upgrades. While it offers substantial cooling improvements, it's important to note that this part is not CARB approved and cannot be shipped to California. For optimal performance and reliability, consider consulting with a tuning specialist to adjust engine parameters after installation.
