Turbosmart 15 Subaru WRX BOV Smart Port Black

The Turbosmart Dual Port valve is a hybrid-type BOV offering three BOVs in one. It can be configured to vent to the atmosphere, back into the air intake, or both. Features a twist top design for quick fine-tuning. The piston is lightweight, fast-acting, and durable. The "check" valve trumped design keeps dirt and debris out, especially useful due to its low mounting location on this vehicle. Requires less maintenance and lubrication. Our latest Type 5 Dual Port BOV, explicitly made for the 2015 WRX, features the innovative new Smart Port drive-by-wire friendly staging technology that gives you the response of a plumb-back valve, with the high-performance benefits of a vent-to-atmosphere valve. The Smart Port system involves a new piston manufacturing process utilizing specialized alloys and coatings and a revolutionary new vent-to-atmosphere trumpet design. These unique designs allow for a swift response while providing enhanced sealing. The result is quicker spool-up and better performance on modern drive-by-wire vehicles. The new Smart Port piston is made from aerospace alloy, reducing the piston’s weight and improving the valve’s response. A new military-spec coating technique is applied to the surface of the piston. This low-friction material also helps make the BOV more responsive than any previous Type 5 BOV. It has excellent wear-resistant characteristics – extending the working life of the BOV. Turbosmart’s new Smart Port trumpet allows a softer spring in the body of the BOV to aid in valve response to the plumb back port while retaining the ability to vent to the atmosphere.
