  • Cap, piston, and flange are CNC machined from 6061 billet aluminum materials
  • Blow off valve body is CNC machined from a single block of aluminum 
  • Anodized red finish
  • High-flow
  • Adjustable relief pressure with adjustable spring tension allows for an adjustment when the blow-off valve vents
  • A looser setting will make it act smooth and more like stock while a harder setting will cause it to vent later and with significantly increased boost levels
  • Adjustable flow control allows you to control the volume of air released when the blow-off valve vents
  • Adjusting the volume of air helps maintain the perfect amount of boost in your system during shifts
  • Recirculating the air recirculates the air back to the intake track to maintain proper air-fuel ratio and driveability between shifts
  • Low maintenance and is quick and easy to disassemble
  • Direct fit and pre-set adjustment
