Featuring two “staged” venting outlets (one for recirc, one for atmosphere), at low valve lifts most of the air is recirculated to keep the noise to a minimum. However, when lifting off the throttle from high boost, the valve opens further and more of the atmosphere venting port is exposed for a louder sound. The kit includes a set of plugs that you can use to configure the Hybrid valves for full recirc, 50/50, or full atmosphere venting to adjust the volume of your blow off sound.

With over 20 years in the business of designing and manufacturing bypass and blow-off valves, GFB have learned a thing or two about managing boosted air, as well as the difference between a good blow-off valve, and a great one! Quality and performance are built into all GFB valves, so regardless of which of our kits you purchase, your investment will last a lifetime (which is why these products are backed by a lifetime warranty) and offer the best possible throttle response and boost holding that any bypass or blow-off valve could deliver.

Our range of bolt on kits for the 2018+ Stinger 3.3L offer many different options when it comes to venting sound, from silent to extremely loud, and anywhere in between. Because the Stinger does not use a MAF sensor, you can vent your BOVs to atmosphere without drivability issues such as backfiring or stalling.

Unbeatable quality, direct bolt-on fit, exclusive venting bias adjustment to control the sound, lifetime warranty, AND a performance benefit – that’s what we mean by Performance Without Compromise.
