GFB 06-10 Mazdaspeed 3/6 / 90-94 Eclipse TMS Respons Blow Off Valve Kit

Take control of your blow-off sound with the GFB Respons, featuring a patented venting bias adjustment system. This innovative technology allows you to infinitely vary how much air is recirculated or vented to atmosphere, giving you the power to customize your BOV sound from silent to ear-shattering!

Like all GFB valves, the Respons utilizes proven TMS Technology to ensure rapid boost recovery on gearshift and optimum throttle response, as well as the ability to withstand boost pressures of 100 psi plus. Say goodbye to backfiring and stalling issues common with fixed-ratio atmosphere-venting BOVs.

  • Patented Venting Bias Adjustment System
  • Infinitely adjustable between full recirc (silent) and full atmosphere (loud)
  • Change the venting bias simply by twisting the adjustment ring
