Description
Upgrade the induction system of your Honda S660 (2015–2019) with the HKS Racing Suction Air Intake Kit. Designed specifically for the S660, this kit optimises air flow from the filter to the throttle, improving response and enhancing performance potential while adding a distinctive, sporty intake sound. The redesigned Hyper Stealth Frame and Super Lip Funnel maximise the effective intake surface area, while the buffed aluminium suction pipe reduces internal turbulence compared with the factory corrugated hose. The result is smoother, more efficient air flow and a sharper throttle feel, particularly beneficial for turbocharged applications. Finished in black with a bold white HKS logo and a polished aluminium pipe, this intake kit also delivers a clean, purposeful appearance in the engine bay. An included air control plate, rain cover and cushion tape help balance sound, protection and day‑to‑day usability, all while remaining compatible with the factory ECU and HKS Flash Editor (Phase 2). Note: Operation on vehicles built after January 2020 has not been confirmed.

Features and Benefits

  • Vehicle-specific design for S660
    Pipe angle and length are tailored to the Honda S660 (2015–2019) for improved induction efficiency and quick throttle response.
  • Redesigned Hyper Stealth Frame
    Increases air intake surface area by approximately 27%, improving air flow efficiency over previous designs.
  • Smoother air flow than stock
    Purpose-designed suction pipe reduces corrugations and internal gaps found in the OEM hose, minimising swirl and resistance for more stable intake flow.
  • Wet two-layer polyurethane filter
    High-flow, wet 2-layer element with special high-viscosity adhesive maintains filtration performance while supporting increased air volume. Compatible with optional dry 3-layer replacement elements.
  • Super Lip Funnel technology
    Signature HKS funnel maximises effective intake area within the tight S660 engine bay, further enhancing intake efficiency.
  • Rigid aluminium back plate
    Anodised black aluminium back plate securely fixes the funnel, improving rigidity, durability and heat resistance while giving a sleek appearance.
  • Frame support for easier servicing
    Frame support guides the filter onto the hemispherical surface, simplifying installation and future filter changes.
  • Sporty but tunable intake sound
    Air control plate allows adjustment of intake sound level to suit driver preference.
  • Protection against water ingress
    Rain cover and cushion tape help prevent water from entering the engine bay and air cleaner area.
  • ECU-friendly design
    Developed to minimise adverse effects on the factory ECU, so resetting is typically not required, and is compatible with HKS Flash Editor (Phase 2).
  • Engine bay visual upgrade
    Buffed aluminium pipe and bold white HKS logo on the black back plate give a clean, motorsport-inspired look.

Note: As a high-efficiency intake, HKS recommends using this kit as part of a total tuning package, ideally combined with a sports exhaust and appropriate engine settings.
