About This Product
If you are looking to restore the fuel efficiency of your Touring or Trike model, these Walker Products O2 sensors are an excellent choice. Made in the USA, these lambda sensors meet or exceed all factory specifications and are built with dual shield ends to handle high exhaust temperatures. They are sold individually and come pre-wired with the correct connectors, making the installation a simple direct-fit process without any need for modifications. This sensor is designed to replace OEM part number 27729-10. Replacing a faulty sensor ensures your ECM can accurately monitor the air-fuel mixture, preventing the sluggish performance and poor mileage often associated with worn-out exhaust sensors.
