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.
The K20C engine was designed for use in a normal road car and features a catalytic converter, removing this converter eliminates its restricting effects which significantly increases the engine horsepower.
HKS developed an extension pipe without the catalytic converter and a frontpipe that will connect it to a catback exhaust system.
Removing catalytic converter results in a more linear boost and throttle response.
Uses 3 inch pipes, compatible with HKS catback exhausts.
A perfect addition to intake, intercooler and other HKS products for future ECU tuning and boostup.
Decreases secondary exhaust gas pressure from turbine and reduces exhaust restriction.
