GFB Respons Dual Port Variable BOV Dual Port Blow Off Valve 35mm/30mm Nissan Silvia/180SX S13/Pulsar GTi-R/300ZX Z32

Purpose-built performance

The GFB Respons Dual Port Variable BOV Dual Port Blow Off Valve 35mm/30mm Nissan Silvia/180SX S13/Pulsar GTi-R/300ZX Z32 is a adjustable dual-port blow-off valve selected for its role in the turbocharged vehicle. The Respons combines recirculation and atmosphere venting with an adjustable venting bias. This gives the driver control over the balance between audible blow-off sound and plumb-back operation, while the valve reacts to pressure changes during throttle transitions. Unlike a generic replacement part, selecting the correct version matters for connection geometry, operating behaviour and the intended vehicle or custom installation.

How it works

Choosing the correct venting strategy is particularly important on vehicles with airflow-metering systems: sound preference should be balanced with the engine management configuration. Valve behaviour and sound will vary with boost pressure and intake layout.

Key Features & Benefits

• Adjustable recirculation-to-atmosphere venting
