Synapse Blow Off Valve Kits


Synapse Engineering now offers a direct bolt-on kit that replaces the factory diaphragm diverter valves with a single, fast-acting piston-actuated Synchronic BOV.

Included in the kit is a black powder coated charge pipe w/ all necessary hardware for a streamline installation. Synapse also includes their signature boost-connect fittings and hoses to finish off the kit. The Synchronic BOV also clears the factory intake airbox with no modifications!

    Updated design elements:
  • Zero weld, CNC mandrel-bent, aerospace grade Aluminum tubing
  • Relocated BOV location closer to the throttle body for improved performance and better clearance
  • Material change to lightweight, aerospace grade Aluminum 6061 in annealed condition for much improved thermal conductivity
  • Reduction of Silicone coupler surface area for maximized charge velocity
  • Billet CNC machined air temp sensor adapter welded directly onto charge pipe
  • T-bolt clamps now included with the kit


The charge pipe included in the kit is bead-rolled so couplers will not blow-off with increased pressure and the supplied bracket mounts to engine so that charge piping & BOV move in unison with engine under all conditions.
