Review HKS Capacity Upgrade 2.1l Low Comp

The HKS 21004-AT003 FA20 2.1L Compact Series Air Intake System is a performance upgrade designed for the Subaru FA20 engine found in various Subaru models, including the Subaru Impreza WRX STI (2015-2019) and Subaru Forester XT (2019-2020). This air intake system, part of HKS's Compact Series, is meticulously engineered to maximize power gains while retaining the factory airbox for a seamless installation process.

The HKS 21004-AT003 FA20 air intake system utilizes a high-flow, conical-shaped air filter. This design allows for a larger filter surface area, increasing airflow and ensuring optimal engine performance. The filter features a multi-layered, oiled cotton media, ensuring a high level of filtration efficiency while maintaining a visually appealing appearance.

The intake pipe is constructed from a durable, heat-resistant, and lightweight material, providing excellent thermal insulation and reducing the intake temperature. The pipe includes a large-bore, 63mm diameter inlet, which increases airflow and reduces airflow restrictions caused by the factory intake.

One of the most notable features of the HKS 21004-AT003 FA20 air intake system is its design. The system utilizes a unique, compact design that allows it to be installed without the need for any modifications to the factory airbox or engine bay. This not only simplifies the installation process but also maintains the factory appearance of the vehicle.

Additionally, the HKS air intake system includes a high-performance, silicone intake hose. This hose is designed to provide a perfect seal and minimize air leakage, ensuring optimal engine performance.

By upgrading to the HKS 21004-AT003 FA20 Compact Series Air Intake System, you can expect an increase in power output, improved engine response, and enhanced overall driving experience. This performance upgrade is an excellent choice for those looking to extract more power from their Subaru FA20 engine while maintaining a factory appearance.
