If you're a proud owner of a Mazda Mazdaspeed 3/6 or Mitsubishi Eclipse (90-94), you know the importance of performance upgrades that deliver real-world benefits. The GFB Respons T9002 Blow-Off Valve is not just another dual-port BOV; it’s a game-changer that enhances both your vehicle's performance and sound profile.
At first glance, the Respons may seem like a standard dual-port blow-off valve, but it’s equipped with GFB's innovative venting bias adjustment system. This unique feature allows you to control how much air is vented from each outlet, giving you the ability to tailor your driving experience.
The venting bias adjustment is simple yet effective. By twisting the adjusting ring, you can open the atmosphere port while simultaneously closing the recirculation port. This allows for venting ratios from 100% recirc to 100% atmosphere, providing maximum flexibility for your setup.
When we say "bolt-on," we mean it. The T9002 comes with everything you need for a straightforward installation. It fits directly in the factory location with no modifications required, making it perfect for DIY enthusiasts.
"Installed the GFB Respons on my 2008 Mazdaspeed 3 and wow! The sound is perfect—loud enough to be heard but not obnoxious. Plus, the throttle response is noticeably better. Highly recommend this upgrade!"
Don’t settle for a generic blow-off valve. Upgrade to the GFB Respons T9002 and experience the difference in performance and sound that your Mazda or Mitsubishi deserves.

It all started with the passion of John Adrian to create something that other aftermarket parts cannot produce. Most parts he encountered are either of low quality and are made out of inferior materials.
He decided to take matters into his own hands and started designing, testing, and developing parts that would help improve the performance of his vehicle. Using his own car as a personal testbed, he created products that other enthusiasts later noticed, which has become the start of Go Fast Bits.
