The box has been opened but the inner plastic is still sealed on this air filter. RC-5102 is the part number. I think it has various applications. The box says off road, racing and marine use. Asking $100.00 or best offer. If you have questions please feel free to ask, I will do my best to answer them.
It is hard to get a good picture of the filter thru the plastic, but I don't want to open it. Sorry.
