Product Description

The Torque Solution TS-SU-751 blow-off valve adapter delivers enhanced atmospheric blow-off tone for Subaru FA24 2.4 L turbo engines while retaining full compatibility with factory ECU mapping and partial recirculation. Ideal for enthusiasts seeking a more aggressive auditory experience without sacrificing daily drivability, this spacer gives you user-tunable sound by allowing you to plug or open any of its nine vent holes.

Constructed from precision CNC-machined 6061 billet aluminum with a durable black anodized finish, the TS-SU-751 is built for long-term performance and aesthetics. Installation is straightforward and completely reversible: retain original BOV functionality while adding sound customization. Note: this part is not CARB legal and is restricted to race or off-road use in regions subject to emissions regulations. Backed by Torque Solution's limited lifetime warranty, it's a practical upgrade for Subaru owners driving FA24-powered Ascent, Outback XT, Legacy XT or WRX through model year 2025.
