GFB Deceptor Pro II Blow Off Valve Kit for Select Subaru 2001-2020 (T9503)
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits select 2001-2020 Subaru Impreza, WRX, WRX STI, and Forester models.
The GFB Deceptor Pro II provides precise control over your blow-off valve volume directly from the driver's seat. Utilizing a motorized drive system, this kit allows you to adjust the venting bias—moving from silent recirculation to a full atmosphere-venting sound, or anywhere in between—on the fly. This eliminates the need to choose between a quiet daily driver and a performance-sounding turbo setup.
Beyond sound, this patented system addresses the technical challenges of venting air to the atmosphere on MAF-equipped engines. By using the in-car controller to limit the maximum venting ratio, you can prevent the rich-running conditions that lead to backfiring and stalling. The Deceptor Pro II offers the signature blow-off sound without sacrificing engine stability or drivability.
- Manufacturer Part Number: T9503
- Adjustment Type: Electronic remote control (included)
- Venting Bias: Fully adjustable from 100% recirculating to 100% atmosphere
- Construction: Precision-machined for high-boost reliability
- Included Components: Blow-off valve unit, in-car controller, and wiring loom
