The Trinity Racing Boost Tube is a high-performance upgrade for the Polaris RZR XP Turbo and RZR Pro XP. 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 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 using an included adapter.

Blow off valve is available separately for a discounted price of $89.99 when paired with a Boost Tube.
