Product Overview

This wastegate solenoid receives vacuum or pressure signals from the vehicle's ECM to adjust the wastegate actuator position, diverting excess exhaust gas away from the turbocharger turbine when boost pressure reaches factory-specified limits to maintain safe operating parameters. It is manufactured to match OEM fit, form, and function for seamless installation and long-lasting performance.
