About This Product
MCS oxygen sensor. This is an OEM-style replacement for the rear muffler position. It carries part number 917609 and has a 12mm thread. Fitment covers the 2025 Fat Boy, 2021 to 2024 Fat Boy S, 2021 to 2022 Breakout S, 2023 to 2025 Breakout, 2021 Slim, 2021 Street Bob, 2021 Low Rider S, 2024 Low Rider ST and 2021 Standard. A failed sensor throws trouble codes and ruins your mixture. This one threads straight in and gives the ECM accurate readings.
Manufacturer part number: 917609.
