HKS Racing Suction Reloaded Subaru Impreza WRX

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 aluminum back plate. Use of aluminum 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.

Frame Support
Fits flexibly to aluminum 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.

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.

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 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.
