EVP Billet Boost Recirculating Valve (BRV) Kits for CFMOTO Z10

EVP DISCLAIMER: Both kits require the EVP Silicone Charge Tube Kit & EVP Intake Tube Kit for proper installation/functionality.

Don’t let boost leaks rob your ride of power! The EVP Billet Boost Recirculating Valve (BRV) for the CFMOTO Z10 delivers unstoppable, leak-free performance. Choose between running your factory Z10 BRV with our Factory BRV Adaptor Kit or fully transform your Z10 with the EVP BRV Kit.

The EVP BRV Kit is engineered to operate consistently without leaks and maintain extremely high manufacturing tolerances. Includes a body, cap, and piston, precision CNC-machined from billet aluminum with tolerances approaching 0.0003 inches. Sliding components are hard anodized and coated to ensure durability throughout the engine's lifespan. The EVP BRV incorporates three sealing o-rings to provide leak-proof operation, unlike the factory design. For each vehicle/engine type we make BRV kits for, the spring rates are properly matched for optimum performance.

EVP BRV Kit:

• Prevents turbo compressor surge, which causes lost performance and decreased throttle response 
• Redirects excess air back into the intake system when the throttle plate is closed
• Plug-and-play resistor included that connects directly to the factory BRV harness, preventing a check engine light
• Protects the longevity of the turbocharger
• The body, piston and cap are machined from billet aluminum and tested to 500+ horsepower
• The cap is anodized and re-machined for easy gripping for spring tension adjustments
• The piston and body are hard coated with impregnated Teflon anti friction matrix
• The design has 3 sealing O-rings for leak proof operation
• Does not have the "pshh" sound that some customers look to avoid
• Proudly machined and made in the USA
• EVP Silicone available in Black or Orange
• Includes a billet “T” barb allowing for EVAP cars run without any engine lights or canister faults

Factory BRV Adaptor Kit:

• Reuses Factory Electronic BRV (Not Included)
• Electronically controlled valve from the ECU
• Includes billet adaptor that fastens to factory BRV
• EVP Silicone available in Black or Orange

What's the Difference Between a Blow Off Valve and a Boost Recirculating Valve?

A blow-off valve (BOV) and boost recirculating valve (BRV) are very similar mechanically and perform similar jobs; they just do it in two different ways. Both valve bodies are attached to the charge tube, and both are designed to release turbocharger pressurized air once the throttle body closes to prevent turbocharger compressor "stalling". Both valves are also connected to a manifold vacuum / pressure port so when the throttle body closes, the manifold vacuum pulls the BRV/BOV piston open and when the throttle blade opens and the manifold sees positive pressure, the piston of the BOV/BRV valve closes. When the BRV valve is open, the built-up pressure in the charge air system gets diverted back to the fresh air side of the turbocharger and helps to keep the turbocharger spooled up when the throttle is being modulated from part throttle to wide open throttle then back to part throttle. This makes the boost response crisper in these throttle modulation situations. A BOV is operated the same way but instead of venting the built-up pressure back to the turbo inlet, a BOV vents most of this pressurized air to the atmosphere and the notorious 'Pssshh' sound is emitted.
