GFB TMS Respons Blow Off Valve Kit T9033 for Select 1991-2015 Mitsubishi, Dodge & Subaru

Fits select 1991-2015 Mitsubishi (Lancer Evolution, Ralliart, Eclipse, 3000GT), Dodge Stealth, Eagle Talon, and Subaru Legacy models.

The GFB TMS Respons Blow Off Valve Kit (T9033) is engineered to eliminate the common drivability issues—such as stalling and backfiring—that occur when using fixed-ratio atmospheric valves on MAF-equipped vehicles. Featuring GFB's patented Venting Bias Adjustment, this valve allows you to manually fine-tune the ratio of air recirculated into the intake versus air vented to the atmosphere, giving you the signature blow-off sound without compromising engine stability.

Constructed for high-performance applications, the Respons utilizes GFB's Turbo Management System (TMS) technology to ensure rapid boost recovery during gear shifts and significantly sharper throttle response. The internal piston and spring assembly are designed to withstand boost pressures in excess of 100 psi, ensuring it will never leak even in extreme forced induction setups.
