About This Product
This MCS oxygen sensor is a reliable OEM-style replacement for the rear muffler position on modern Softail models. It features a 12mm thread and is built to provide accurate readings to the ECM for optimal engine management. Fitment includes the 2025 Fat Boy, 2021 to 2024 Fat Boy S, 2021 to 2022 Breakout S, and 2023 to 2025 Breakout. It also fits the 2021 Slim, Street Bob, and Low Rider S, as well as the 2024 Low Rider ST and 2021 Standard. Carrying OEM reference 917609, this sensor is a direct swap for a failed factory unit, ensuring your Milwaukee-Eight engine continues to run efficiently without throwing trouble codes.
Manufacturer part number: 917609.
