Overview

The MODE Auto Concepts T9007 Respons TMS is a direct-fit blow-off valve designed for specific Subaru models. It features GFB's patented venting bias adjustment system, allowing users to control the sound level from fully recirculating to fully atmospheric, or anywhere in between. This system helps prevent stalling and backfiring, even on sensitive MAF-based systems. The valve also offers improved throttle response and faster boost recovery on gearshift.
Show original supplier description
The MODE Auto Concepts T9007 Respons TMS is a direct-fit blow-off valve (BOV) engineered for Subaru vehicles including the WRX VA (2015-2021), Forester XT SJ (2013-2018), and Levorg (2016-on). This valve distinguishes itself from standard dual-port BOVs with GFB's patented venting bias adjustment system. This unique feature allows precise control over the ratio of air vented to atmosphere versus recirculated air, enabling users to customize the blow-off sound from silent to maximum noise, or any level in between. Beyond sound customization, the Respons TMS aims to enhance performance. It can also prevent issues like stalling and backfiring commonly associated with atmospheric venting BOVs, even on sensitive MAF-based systems, by carefully managing vent volume and duration. The kit includes everything necessary for installation. The product is constructed to offer performance and sound without compromise, addressing common concerns about BOV compatibility with factory airflow meters.
