Spoon Sports Radiator Caps. Spoon Sports is one of the premiere Japanese companies focused on Hondas. Just about all their products have been tried and tested on race tracks from the world over. A small company for sure, but one every bit as committed (if not more) as the larger ones. If you want to extract every single ounce of available power and handling out of your Civic, Integra or S2000 then Spoon Sports is the way to go.
