Proflow’s LS water cross over kits eliminate trapped air and steam from your cylinder heads, preventing hot spots and overheating. This can cause head gasket failures, lean cylinders and pre-ignition. They connect to the vent ports on each corner of the cylinder heads (2 port or 4 ports options available), which is then routed to either the radiator or water pump. This kit includes stainless steel PTFE black braided hose and the appropriate fittings and distribution blocks for a simple installation. They also offer a more attractive look than the OE rigid hard lines and provide flexibility when using aftermarket intakes and other accessories on performance LS vehicles.
