EVP Billet Blow Off Valve (BOV) Kit for Polaris RZR

Evolution Powersports was first in the industry to design and produce a Blow Off Valve (BOV) specifically for small displacement factory turbocharged engines. Virtually every BOV on the market was designed for automotive applications which have different requirements in terms of spring rates and flow capacity vs a powersports engine. Back in 2015 we decided to take a no-expense-spared approach to designing a BOV specifically for the powersports market.

No other BOV on the market offers the quality and fine-tuned refinement like an EVP BOV.
