Same Day Shipping KS SUPER SQV4 RETURN KIT PLUS FL5

Unleash the signature blow-off sound and protect your turbo system with the HKS SUPER SQV IV Return Kit Plus, engineered specifically for the 2023+ Honda Civic Type R (FL5). This kit combines high-performance response, aggressive acoustics, and OEM-grade fitment in one precision-engineered package.

Key Features

• Turbo Protection
  The sequential valve design releases excess boost pressure instantly during throttle lift to prevent compressor surge and prolong turbocharger life.
• Responsive Performance
  Unlike spring-based valves, the HKS SSQV IV uses a pull-type relief valve that operates consistently regardless of boost pressure—ensuring fast, stable operation under all driving conditions.
• Signature Sound
  Produces HKS’s iconic high-pitched “chirp” under boost, giving your Civic Type R a sharp, race-inspired tone.
• Stealth + Style
  Finished in sleek silver and mounted prominently in the engine bay, the valve adds a visual upgrade that matches its performance.
• Suction Return Hose Included
  Designed with a return line for closed-loop setups—ideal for regions requiring recirculation or for drivers who prefer quieter, OEM-like function.
