This is an aftermarket tachometer. I don't know if it's genuine. Therefore, I'm selling it at a bargain price. I'm selling it to organize my collection. It's new and unused, but it has been stored at home, so please refrain from purchasing if you are sensitive to this. Please understand that I have not tested the operation before purchasing. [Compatible Number of Cylinders] 4, 6, 8 cylinders [Dial Color] Black Please note that the outer box may have some dents. Thank you.
