HKS Super SQV 4 BOV Return Kit for 2017+ Honda FK8 Civic Type-R

HKS Super SQV (Sequential Blow Off Valve) uses a unique sequential valve structure and a differential pressure control system, which allows for a broad operating range from low boost to high boost. Its Pull-Type relief design ensures stable operation regardless of the amount of boost pressure. This Super SQV maximizes the charge-response that repeats pressure-charging and pressurized air relief by throttle on and off and supports new generations of turbocharged vehicles.

Factory recirculation valve sound cannot be noticed, but once HKS Super SQVⅣ is installed, its unique & sharp high frequency sound demonstrates its existence. 　 Super SQVⅣ significantly increases its presence and improves the engine compartment appearance. To match with the appearance created by HKS Intercooler Piping Kit, the buffpolished casting pipe is included. By both the sound and appearance, Super SQVIV increases the fun to drive.
