A turbo frequency valve, also referred to as a boost pressure solenoid valve or wastegate frequency control valve, monitors the amount of boost generated in a turbocharged engine by opening and closing the wastegate. They can be installed on both upgraded and stock turbochargers and are a great way to optimize turbocharger performance. In fact, without a properly functioning turbo frequency valve, the unchecked boost levels could cause major damage to both the turbo and the engine. Luckily, TurboTurbos offers various turbo solenoid valves to help you better maintain and boost your turbocharger. Browse today to find the right options for your system.
