Hybrid Dual Outlet Blow-Off Valve for Hyundai Smartstream Engines

The GFB T9214 Hybrid Dual Outlet Blow-Off Valve is engineered specifically for Hyundai models equipped with the Smartstream 1.6T-GDI turbo engine, delivering a tailored balance of blow-off sound and controlled boost release without compromising drivability.

Configurable Venting for Enhanced Sound and Response

Featuring a dual-outlet design with staged venting, the Hybrid valve allows you to adjust the balance between recirculated air and atmosphere venting. This versatile setup enables a range of sound profiles — from quiet recirculation to aggressive blow-off tones — depending on your preference, while ensuring stable boost control and throttle response. You can also opt for a whistling trumpet (sold separately, part #5702) for a different sound.

Key Benefits

• Adjustable venting bias — recirculate, 50/50 or atmosphere
• Improved throttle response and boost control compared to stock valves
• Durable construction for performance and longevity
• Includes configuration plugs for tailored sound output

Designed for Smartstream Turbo Engines

Unlike generic blow-off valves, the T9214 is developed specifically for Hyundai’s Smartstream turbocharged engines, retaining excellent drivability while allowing control over how much air is vented to atmosphere. Whether you want a subtle boost release or a more pronounced blow-off sound, this valve delivers sound and performance in equal measure.
