CDI Box from a 1985 Arctic Cat Cougar 500. Acquired in parts lot with some other parts so I was not able to live test it but I believe it to be in working order and I can work with you if there happened to be an issue. Appears in reasonable used condition with normal signs of use and age, some corrosion, stains, etc.. What is pictured is what will be included. You should check to be sure this will fit your machine before purchasing.
