HKS RS CT9A EVO7 4G63 - HKS70020-AM102

HKS RS CT9A EVO7 4G63 is a performance air intake system designed for the Mitsubishi Lancer Evolution VII (CT9A, 4G63 engine) produced from 01/2001–03/2005. This kit replaces the stock intake to improve air intake efficiency, enhance throttle response, and provide a distinct sporty intake sound.

• Engine: Designed specifically for 4G63 turbo engines.
• Model Compatibility: Fits CT9A Evolution VII only (not compatible with GT-A automatic models).
• Filter Type: Super Power Flow (Red) with a redesigned, high-efficiency "Hyper Stealth Frame".
• Structure: Includes polished aluminum piping that reduces airflow resistance compared to stock corrugated hoses.
• Performance: Improved engine response, especially at low-to-mid range speeds.
• Tuning: While the kit improves performance, engine tuning or resetting (e.g., via HKS F-CON) may be required due to increased airflow.
• Spark Plugs: HKS recommends upgrading to heat-resistant spark plugs.
• Maintenance: The Super Power Flow air filter should be changed regularly to maintain performance.
