Coolant flow restrictor cone

Regular price $12.99

If you're losing water in a non pressure radiator at higher speeds, flow restriction is a useful remedy. Place this cone inside your top hose connection..  Mark it the ID and cut the tip and base to achieve the preferred diameter for lower flow rate.   

Three cones pictured but you are buying one cone with an OD of 1.6" and height of 1.5"
