TSP Chrome Aluminum -20 AN LS Water Pump Adapter Kit HC8939

If you’ve made performance upgrades to your LS engine, chances are the stock push-on radiator hoses won’t cut it. Make the necessary switch with this conversion kit from TSP. With a water outlet and and weld-on inlet adapter, this converts both to -20 AN. Also included is an adapter plate with a rubber o-ring for use with older LS water pumps.
