About This Product
Maintaining the correct air-fuel ratio is critical for performance and fuel economy, and this MCS oxygen sensor is built to handle the job. This 12mm threaded, OEM-style sensor is designed for use in the rear header pipe, crossover section, or muffler locations depending on your specific model. It fits a vast array of modern Harleys, including 2021 to 2025 Softail models like the Fat Boy, Breakout, and Low Rider S, as well as 2021 to 2025 Touring and Trike models like the Road King and Street Glide. Whether you are replacing a fouled sensor in the rear head pipe of a Softail or the crossover section of a Road Glide, this component, matching part 917668, ensures your fuel injection system stays perfectly calibrated.
Manufacturer part number: 917668.
