HKS Racing Suction Air Intake for Subaru Impreza WRX/STI GDA/GGA / Forester SG / Legacy

Reduce turbo lag and enjoy a smooth improvement in response under acceleration from mid-high rpm range.

Installing this product does not affect the OBDII feedback; therefore, ECU resetting is not required in order to use this product. (Some vehicle may require resetting.)

Remarks

The Racing Suction is air cleaner for engine. Please change the Super Power Flow filter regularly for the best result.

Please change for the heat resistant type Spark spark plug because you will have more engine output with this item installation. Especially for higher power sport racing you must change it!

This item is produced from the stock vehicle, but you might need to reset for adjustment of the air flow meter output device or fuel related devices (such as F-CON) because there are many different types of vehicles.

RACING SUCTION

The most powerful intake system carefully designed to fit engine room of a vehicle. HKS Racing Suction pushes air intake system efficiency to the limits.

Stealth frame is redesigned!

"Hyper Stealth Frame" exceeds the performance of previous Super Stealth frame.

Increasing air intake surface area by 27% improves air intake efficiency.

Bold white HKS logo printed on black anodized back plate accentuates the engine bay!

The outer edge of the funnel is securely fixed to the aluminium back plate. Use of aluminium significantly improves rigidity and durability. Alumite process improves surface of the funnel and also provides a sleek black look.

TECHNOLOGY

Vehicle specific suction pipe design.

Angle and length of pipe enhance the induction efficiency.

It is effective for quick response for NA engines and higher performance for turbocharged engines.

Point

With stock suction system, induction air hit to corrugated portion of hose and makes swirl and resistance. The specially designed pipe reduces corrugated portion and gap inside pipe to make air flow smoother.

Features

Frame Support

Fits flexibly to aluminium back plate, securely fixes hyper stealth frame. It also serves as a guide for attaching the filter to the hemispherical surface, improving maintainability such as filter replacement.

Racing suction adopted wet two-layer type

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.

* Dry type three layer type exchange filter can also be used

Super Inner Frame

The cross section of the inner frame is streamlined with 16 frames parabolically placed towards the center.

Simple lightweight frame design provides smoother air flow.

Super Lip Funnel

The defining feature of HKS intake: "Super Lip Funnel".

Super Lip Funnel maximizes air intake surface area in the limited space in the engine bay and optimizes air intake efficiency.

NOTE

HKS Racing Suction is a high efficiency air intake device and may cause irregularities in the engine work. HKS recommends considering a total tuning concept combining this product with a sport exhaust system and a suitable engine setting.

■Direct Throttle（Compressor）intake Mounting

Replacing all necessary parts between the HKS air cleaner assembly and the throttle (to the compressor housing on turbo cars) allows eliminating air intake restrictions and increasing air intake efficiency, providing a dramatic improvement in engine response and performance. Exclusively for some vehicles only, a direct type Super Power Flow air cleaner assembly is available. It provides a smooth air flow from the entrance point of the filter to the throttle valve.
