HKS Blow Off Valve
Product Description
Blow-Off Valves prevent compressor surge
which occurs when the throttle plate of a turbocharged engine
closes and the air is forced back into the turbocharger’s
compressor housing causing the turbo to slow down. Compressor
surge not only decreases the spool of a turbo but can also
damage its center cartridge. HKS Blow-Off and Bypass Valves
prevent compressor surge by venting the excess pressure when a
throttle plate closes, thus improving spool-up &
longevity.
