The Tial QR BOV is designed for use on turbo-charged and super-charged applications (Paxton, Vortec, etc.). The body and all internal components of Tial's BOV are CNC-machined from 6061 Aluminum Alloy. The V-Band mounting clamp is made of Stainless Steel hardware for a long lasting, and corrosion-free appearance. The valve seal included with this BOV, utilizes a Viton O-ring that is clamped in place to prevent the possibility of sticking to the seat and pulling out. The valve stem and guide are Teflon-lubricated and hard anodize-coated for wear resistance. Also included is Tial's own machined Aluminum banjo-type air fitting and bolt, with over sized 10mm hose barb, for quick actuator response. The actuator has a high temp silicone Nomex-reinforced diaphragm for long life. Each unit is furnished with an Aluminum, Mild Steel, or Stainless Steel mounting flange, and is available in a variety of colors to help set off your engine bay.
