HKS Super SQV IV Blow Off Valve Kit β Honda Civic Type R FL5 (K20C)
Sharp boost response. Signature sound. Street and track ready.
The HKS Super SQV IV Blow Off Valve Kit for the FL5 Civic Type R is engineered for enthusiasts seeking sharper throttle response, stable boost control, and the iconic high-pitched blow-off note that defines the HKS SQV. Whether you're aiming for a compliant street build or an aggressive track setup, this kit delivers performance and flexibility.
Overview
The SQV IVβs sequential valve system provides lightning-fast pressure relief when the throttle is closed, reducing strain on the turbocharger and enhancing long-term reliability. It holds boost confidently under high-load situations without premature venting, ensuring consistent power delivery across throttle transitions.
Designed for a visible engine bay install, the SQV not only delivers audible excitement but also adds visual impact under the hood. The included suction return hose supports a closed-loop (recirculated) setupβideal for maintaining smooth drivability and compliance with emissions regulations in road-legal applications.
Key Features
- Rapid Boost Relief: Instantly vents excess pressure when lifting off the throttle, minimizing compressor surge.
- Stable High-Boost Performance: Maintains pressure under load without unnecessary bleed-off.
- Iconic SQV Sound: Emits HKSβs signature high-frequency chirp when vented to atmosphere.
- Engine Bay Presence: Prominently mounted for aesthetics and sound clarity.
- Dual Setup Compatibility: Includes suction return hose for recirculation and road legality; supports atmospheric setups for track use.
