The Evolution Powersports Polaris RZR XP Turbo diverter valve (blow off valve) is constructed of anodized billet aluminum and features very high temperature sealing o-rings.
The OEM Polaris part is constructed of plastic and is a very low quality part which is prone to sticking open which will dump boost pressure to back into the intake and will cause a loss in power.
The EVOPS BOV is a precision part that is designed for high performance vehicles (it has been tested to over 500 hp!) and is a direct replacement for the OEM valve.
Many different spring rates have been tried to maximize the performance and fine tune the transition from where the valve is open/closed for smaller displacement turbo/supercharged vehicles.
