About This Product
Walker Products stock replacement lambda sensor. USA-made. Replaces Harley-Davidson OEM 27729-10. Fits Touring and Trike models. On these bikes, if the mixture is off or fuel consumption jumps, the lambda sensor is usually to blame. This one is pre-wired with the correct connector for a direct fit. Dual shield ends stand up to the heat. Install it and the ECM gets good exhaust gas data again for proper fuel trim. No wiring modifications needed. Sold individually.
