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, which is then routed to either the radiator or water pump. This kit includes stainless steel hard line tubing 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. Will not suit factory intake manifold (requires 25mm of clearance under the manifold).

Suits the following engines:

• LS1/LS6
• LS2/LS3/L76/L77/L98
