HKS 71008-KH009B Super SQV4 Black Edition BOV Honda Civic Type R FK8

Vehicle Fitment

• 2017-2021 Honda Civic Type R (FK8, K20C1, Turbocharged) - All variants

Fitment Notes

• Vehicle-specific kit - includes the SQV4 Black Edition head unit and a vehicle-specific buff-polished casting pipe for the FK8 Civic Type R. No additional adapters are required for installation on the listed vehicle.
• Compatible with the HKS Intercooler Piping Kit for the FK8 (Part No. 13002-AH001) - the buff-polished casting pipe is designed to complement the HKS intercooler piping aesthetically and functionally.
• This is the Black Edition colour variant of the standard HKS Super SQV4 FK8 kit (71008-AH009). Valve internals, specifications, and performance characteristics are identical to the standard version.
• The SQV4 uses the same mounting flange as all previous HKS SSQV generations - compatible with all optional HKS SSQV inserts, recirculation fittings, and recirculation kits.

Features

• Super SQV4 (Sequential Blow-Off Valve, 4th generation) - HKS's flagship blow-off valve featuring a unique sequential valve structure with primary and secondary valves for precise pressure management across all boost levels from low to high.
• Black Edition exclusive finish - the valve body and upper section are finished in semi-gloss black paint, while the funnel is finished in wrinkle black paint. The combination delivers a premium, understated quality aesthetic versus the standard silver finish - suitable for builds where visual cohesion and a darker, more restrained engine bay appearance is preferred.
• Buff-polished casting pipe - the vehicle-specific installation pipe is finished with a buff polish for a contrasting premium look against the black valve body, designed to visually complement the HKS Intercooler Piping Kit (13002-AH001).
• Sequential valve structure - the primary and secondary valves activate progressively as boost increases, providing stable, precise pressure control from low boost through high boost without the compromises of a single-valve design.
• Differential pressure control system - responds to the differential between boost and manifold pressure for accurate, stable operation across all boost conditions and engine loads.
• Pull-type relief design - vacuum-actuated mechanism ensures consistent, leak-free seating under boost regardless of boost level.
• Distinctive sharp, high-frequency sound - the Black Edition produces the same characteristic SQV sound signature as the standard version - a sharp, high-pitched blow-off note favoured among front-wheel-drive performance car enthusiasts.
• Holographic HKS authentication logo - cast into the valve body alongside additional HKS logos for genuine product verification.
• Compatible with all SSQV accessories - uses the same mounting flange as all previous SSQV generations for backwards compatibility with inserts, recirculation fittings, and optional kits.

Product Description

The HKS 71008-KH009B is the Super SQV4 Black Edition blow-off valve kit for the 2017-2021 Honda Civic Type R FK8 (K20C1). A special colour variant of the standard FK8 SQV4 kit (71008-AH009), the Black Edition features a semi-gloss black finish on the valve body and upper section with a wrinkle black funnel - delivering a premium, understated aesthetic that suits builds where a darker, more cohesive engine bay appearance is preferred over the standard silver finish. The valve internals, specification, and performance characteristics are identical to the standard version.

The kit includes a buff-polished casting pipe specific to the FK8 Civic Type R, designed to complement the HKS Intercooler Piping Kit (13002-AH001) both visually and functionally. The SQV4's sequential valve structure uses separate primary and secondary valves that activate progressively with boost level, providing precise pressure management and stable operation across the full boost range without leaking at lower pressures. The pull-type relief mechanism ensures consistent seating under boost, and the differential pressure control system responds accurately to changing boost and manifold conditions. The distinctive sharp, high-frequency blow-off sound characteristic of the SQV4 is retained in the Black Edition. The valve uses the same mounting flange as all previous SSQV generations, maintaining full compatibility with optional inserts, recirculation fittings, and ancillary kits.
