FITMENT NOTE: This BOV kit is only compatible with 2020-and-newer Can-Am Defender HD10 models equipped with the EVP DT-130 Turbo System.

If you're adding the EVP DT-130 Turbo System for Defenders, our new BOV kit is a must-have addition to help prevent compressor surge and lost performance, while prolonging the lifespan of both your turbo and engine.

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-expenses-spared approach to designing a BOV specifically for the powersports market.

For a BOV to work consistently and not leak, tolerances must be held to an extremely high standard. The EVP BOV body, cap and piston are precision CNC machined from billet aluminum with tolerances that approach within .0003". The sliding components are hard anodized and coated so the BOV will last the lifetime of the engine. For each vehicle / engine type we make BOV kits for, the spring rates are properly matched for optimum performance.
