The Dynojet Boost Tube is a high-performance upgrade for the Polaris RZR XP Turbo.  This kit does not include a blow-off valve and air filter. Designed to outlive your RZR, its 4-layer reinforced silicone walls can handle the elevated pressures and temperatures that are present in stock or modified trim.  When it’s time to relieve the pressure as the throttle closes the not-included blow-off-valve can be configured to recirculate the air back into the stock plenum or vent it to atmosphere through the air filter.  A  provision to re-use the original TMAP sensor is incorporated and constructed of heat-resistant polymer to avoid conductive heat soak into the sensor
