Kinugawa Turbo Recirculation Bypass Compressor Valve (BCV) — Honda Civic 2.0T Type R FK8 / FL5

The Kinugawa Bypass Compressor Valve (BCV) is a direct-fit, adjustable recirculation valve engineered for Mitsubishi TD04-series turbos with a factory BCV port on the compressor housing. Unlike a blow-off valve (BOV), the BCV recirculates compressed air back into the intake, preserving boost response and protecting the turbocharger on closed-throttle events — making it the preferred choice for street-driven and track-prepared turbocharged vehicles.
