About This Product
This MCS oxygen sensor provides an OEM-style replacement for the rear muffler on specific Softail models. It features a 12mm thread and is engineered to meet factory specifications for accurate exhaust gas monitoring. Fitment includes the 2021 Heritage Classic, 2021 to 2024 Heritage Classic S, and the 2024 Hydra-Glide Revival. Identified by OEM reference 917666, this sensor is critical for maintaining the efficiency of the fuel injection system. If your bike is experiencing a drop in performance or an increase in fuel consumption, a fresh sensor can often be the fix. It is a direct plug-and-play component that helps keep your Milwaukee-Eight running at its peak.
Manufacturer part number: 917666.
