[OE Design]: This air check valve is manufactured to the OEM specification to provide factory-fresh appearance and direct-fit. Installation is easy and doesn't take much time or require special tools. No more check engine light and better
[Emission Control]: A failed check valve can cause check engine light to illuminate and exhaust emissions to increase. A new check valve promotes combustion of unburned fuel by injecting air into the exhaust pipe when the engine is started, thus reducing harmful emissions, especially during cold starts
