We have found a huge need for these for the 2016-2021 Polaris Xpt/ Turbo S RZR. Stock coolant tanks intermingle antifreeze for the air to water intercooler and engine radiator. This causes your intercooler heat exchanger to not run as cool as possible. Our design completely separates the 2 systems and in turn will drop your intake air temps. Split tanks are made with aluminum and are tig welded in our facility. MADE in the USA. Split tanks are sold in RAW, finish.
