The iconic Synchronic BOV that has set the standard for impossibly fast response from a BOV/DV. Completely modular, it can be installed as a vent-to-atmosphere BOV or re-circulating diverter valve. This universal package can be outfitted to most any application utilizing our interchangeable mounting flange system. By design, it is a pull-type valve only.

It operates in a normally open condition. This means that it is designed to remain open under vacuum conditions. or maximum performance and reliability, it is recommended to install the Synchronic BOV in a re-circulated configuration with the discharge between the MAF sensor and turbocharger inlet.
