Billet Coolant Ball TopThis is a billet aluminum version of the top half of an MK4 5 6 OE coolant ball. It has been machined from one solid piece of 6061 aluminum giving it a very clean appearance. The top has a large center port machined to accept an VW MK4 7 style coolant cap, a 1 4" NPT port, and also a 1 4" 28 vent port with a stainless vent tube (not pictured) included. The base of the top has a step machined into it to center it into a matching hemisphere or cylinder.
