HKS has just announced the availability of its new Racing Suction Kit for the Subaru WRX STI. The Racing Suction Kit is widely recognized as being the most powerful intake system from HKS. It is expertly engineered to move as much air as possible while still fitting seamlessly under the hood of your specific make and model. The HKS Racing Suction Kit takes air intake system efficiency to new heights, boasting optimal performance and superior airflow thanks to the open-type filter and aluminum pipe.
The HKS Racing Suction Kit for the Subaru WRX STI is strategically crafted to take advantage of the restrictions in the car’s stock intake and release some of the hidden ponies. The filter element is a unique wet type of foam that improves efficiency without compromising filtration properties. The super funnel lip ensures a steady stream of airflow and increases overall velocity too. The HKS Racing Suction Kit for the Subaru WRX STI delivers a perfect balance of efficiency and performance, making it one of the best and most sought-after intake systems on the automotive aftermarket!

Stealth Frame Redesigned: The HKS “Hyper Stealth Frame” exceeds the performance of the previous Super Stealth frame, and increases the air intake surface area by 27 percent to improve efficiency.
Enhanced Appearance: This intake sports a bold white HKS logo printed on a black anodized backplate to accentuate your car’s engine bay!
Frame Support: It fits flexibly to the aluminum backplate and securely fixes to the hyper stealth frame. It also serves as a guide for attaching the filter to the surface to improve maintainability (i.e. filter replacement).
Super Inner Frame: The cross-section of the inner frame is streamlined with 16 frames parabolically placed towards the center. The simple and lightweight frame design delivers smoother airflow for optimal performance.
Super Lip Funnel: The defining feature of HKS Racing Suction intake is its “Super Lip Funnel”. The Super Lip Funnel maximizes the air intake surface area in the limited space in the engine bay and optimizes air intake efficiency.
Filter Element: The HKS Racing Suction Kit adopts a wet two-layer type filter system. The filter element is a wet 2-layer polyurethane form impregnated with a special high-viscosity adhesive. Filter porosity is designed as large as possible to provide high air intake flow efficiency without sacrificing filtration ability.
Note: A dry three-layer type exchange filter can also be used.
Features:
- Polished aluminum pipe improves engine bay appearance.
- Delivers a distinct and attractive induction sound.
- To improve air intake efficiency, HKS changed from a flexible stock rubber hose to an aluminum pipe. This significantly reduces airflow restriction during the HKS flow bench test compared to the stock intake system.
- Removable air duct (air guide) has a newly designed, wider opening. This can be directly used with the stock ECU with the factory setup or with a custom muffler. You can reduce more air intake resistance, by removing the air guide. (*)
(*) ECU setting is required during combination use of the metal catalyzer or removing the airflow adapter guide.
Kit Includes:
- Super Power Flow (open-type filter)
- Aluminum Suction Pipe
