The HKS Racing Suction Kit is a high-performance open air intake system developed for the Subaru WRX STI EJ25 (2009-2014) equipped with the turbocharged EJ257 engine. Replacing the factory intake system with a high-flow HKS intake, it provides improved airflow and reduced intake restriction. The result is quicker throttle response, improved engine performance, enhanced power delivery, and a more responsive driving experience.

The system features HKS's Hyper Stealth Frame, which increases the filter surface area by approximately 27% for improved airflow and intake efficiency. The innovative Super Lip Funnel optimises airflow even in confined engine bay spaces, while the wet two-layer polyurethane filter combines high airflow capacity with effective dust filtration. The vehicle-specific suction pipe is engineered to optimise airflow to the turbocharged engine, producing a sporty induction sound and a more pronounced turbocharger sound, while the improved airflow may contribute to quicker boost response depending on the engine setup.

A black anodised aluminium back plate enhances rigidity, durability, and engine bay appearance. The vehicle-specific design ensures OEM-style fitment and direct bolt-on installation without extensive modifications. Built with HKS's renowned quality and motorsport heritage, the Racing Suction Kit is an ideal upgrade for both standard and performance-modified turbocharged vehicles intended for street and track use.

In October 1973, two talented and young engineers had a vision; to design and build high performance engines and components that major OE manufacturers could not, or would not, produce. HKS pioneered the Japanese aftermarket industry by delivering a host of exciting new products, including the first commercially available electronic turbo timer and boost controller. Other early products included piggy-back ECUs and sophisticated fuel management tools. HKS was clearly driving performance trends for Japanese vehicles forward!
