If I have to replace the sensor is there an aftermarket option or is that a dealer-only item because they are unique to HD?


I mentioned I replaced the spark plugs and someone asked about what I replaced them with. I went to NAPA and got the Champion equivalent. 2-bucks each. Work fine.


as always, thank you for your help.
