Product Description
Turbocharger bypass valve (also known as blow-off or pop-off valve) for Maserati Biturbo, 3200 GT, Ghibli, and Quattroporte models equipped with forced induction systems. Part number 571365700. This valve is designed to release excess boost pressure when the throttle closes, preventing compressor surge and protecting the turbocharger assembly.
The valve operates via vacuum signal from the intake manifold, opening momentarily to vent or recirculate compressed air. Constructed from pressure-resistant alloy with an internal spring-loaded piston, the unit restores correct boost regulation and drivability under rapid throttle transitions.
