Forge Motorsport Dump Valve/ BOV for 2023+ Toyota GR Corolla (FMDV34A)

The Forge Motorsport Blow Off (Dump) Valve for the Toyota GR Corolla Turbo engine is a high-performance upgrade designed to replace the stock electronically controlled bypass valve (OE Part no. 7.04654.08). This valve is recommended for vehicles with increased boost from ECU upgrades or those in warmer climates, addressing common failures that can lead to unnoticed power loss. The Forge valve offers a piston-based design, eliminating the diaphragm, which is prone to failure in the stock version, and is made from durable aluminium billet. It maintains OEM ECU control and comes in both atmospheric (with sound) and factory-style (quiet) options.
