Fits 2016-2021 XP Turbo Models Including Turbo S & 2020-2023 Pro Xp/Turbo R, Assembled in the USA! Many competitors may offer other BOV's that look similar, but we hand build each one her at AA to make sure they hold up to off road abuse, and last as long as possible. Every RZR Turbo should have this blow off valve! The stock BOV (Often referred to as the diverter valve) is made of plastic and is known to warp. Warping can cause a leak in boost pressure which means a loss in horsepower!
