The Mazda 3 MPS Hybrid Valve is a professional-grade, dual-piston unit that combines the functionality of the factory diverter valve (DV) with a blow-off valve. It features two channels: one returns air to the system as in the original valve, while the other vents to the atmosphere, producing the distinctive "PsssssT" sound. This solution is particularly useful when the ECU does not tolerate replacing the factory Bosch valve with an atmospheric blow-off valve, preventing errors such as the Check Engine light.
