The Stealth frame is redesigned!

"Hyper Stealth Frame" exceeds the performance of the 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.


Real sports


Vehicle specific suction pipe design. The angle and length of pipe enhance the induction efficiency. It is effective for quick response for NA engines and higher performance for turbocharged engines.




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.



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. 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.



  • Smooth revolution at high rpm and torque at middle rpm will be increased.
  • Intake sound will be sporty and exciting.
  • It does not affect to air flow meter output.
