The 657449 O2 EFI Sensor is a genuine OEM E-Z-GO / Cushman oxygen sensor designed for vehicles equipped with the Kawasaki 13.5-hp EFI engine. This sensor plays a critical role in monitoring exhaust oxygen levels, allowing the ECU to properly adjust the air-fuel mixture for optimal performance, fuel efficiency, and emissions control.
Replacing a faulty or failing O2 sensor helps restore smooth engine operation, proper fuel mapping, and prevents drivability issues such as rough running or poor fuel economy. This listing includes the sensor only and is intended as a direct-fit OEM replacement—no modifications required.
