HKS RS Intake System for 2015-2021 Subaru WRX and STI 70020-AF108

HKS RS Intake System offers a performance upgrade for 2015-2021 Subaru WRX and STI models seeking to improve power output and aesthetics. This meticulously crafted system replaces the stock intake components with a high-flow design, promoting increased airflow and potential performance gains.

Enhanced Airflow and Potential Power Increase:

• Improved Air Intake Efficiency: HKS replaces the stock rubber hose with a high-flow aluminum pipe. This reduces airflow restriction compared to the stock system, as demonstrated on the HKS flow bench. The improved airflow efficiency can potentially lead to increased engine power.
• Cold Air Induction: The system is designed to promote the flow of cold and oxygen-dense air to the engine. This cooler air can contribute to a more efficient combustion process, potentially leading to additional power gains.

User-Friendly Design and Distinctive Sound:

• Removable Air Duct: The HKS RS Intake System features a newly designed removable air duct with a wide opening. This duct can be used with the stock ECU for both unmodified vehicles and those with aftermarket mufflers. Removing the air duct can further reduce intake resistance for even greater airflow.
• Polished Aluminum Pipe: The polished aluminum pipe not only improves engine bay aesthetics but also enhances durability compared to the stock rubber hose.
• Distinctive Sound: The HKS RS Intake System produces a unique and desirable intake sound, adding to the driving experience.
