Turbosmart Gen-V IWG Twin Port Internal Wastegate Actuator - Black 14psi for BorgWarner EFR (TS-0620-4012)

Fits BorgWarner EFR Series B1 and B2 single and twin scroll turbochargers.

The Turbosmart Gen-V IWG (Internal Wastegate Actuator) provides unparalleled boost control by incorporating the award-winning technology from the Gen-V external wastegate range into a compact internal actuator. Designed for high-performance applications, this actuator features true twin-port control, providing a much wider boost window and more precise tuning than standard single-port designs.

This setup ensures reliable performance and eliminates rod binding under high heat and pressure. The Gen-V cap includes dual 1/8 NPT reference ports for versatile plumbing options.
