Description

The GFB T9001 Respons TMS Blow-Off Valve Kit is engineered to provide adjustable sound and improved performance for select Subaru vehicles. This kit features GFB's patented Venting Bias Adjustment system, which allows for precise control over the split between atmosphere venting and recirculating air. This unique capability allows users to tailor the blow-off sound from completely silent, mimicking factory operation, to a maximum atmospheric release, or anywhere in between to suit their preference. Beyond sound customization, the Respons T9001 addresses common issues associated with atmosphere-venting blow-off valves on sensitive MAF-based systems, such as stalling and backfiring. By carefully managing the venting bias, the valve can deliver the desired blow-off sound without negative side effects on engine operation. Constructed with a balanced piston design, the Respons T9001 is built to withstand high boost pressures, rated for over 100psi, ensuring it can hold more boost than most turbos can produce. The kit is designed as a direct bolt-on, fitting directly into the factory location without requiring separate adaptors or modifications to the vehicle. This ensures a straightforward installation process. This product is not CARB Legal and cannot be sold in California or other states that have adopted California emissions standards. Compatibility is specified for 2008-2010 Subaru WRX and 2005-2009 Subaru Legacy GT models.
