AEROFLOW LS STEAM PIPE CROSSOVER KIT HARDLINE DISTRIBUTION SETUP

The Aeroflow Performance GM LS water cross-over kit (AF64-2197) delivers a clean, high-performance solution for purging trapped air and steam from your engine cooling system. By linking all four corners of the cylinder heads via 1/4″ 304 stainless steel hardlines and a compact central distribution block, this kit prevents steam pockets, hot spots, pressure spikes, and catastrophic head gasket or cylinder failures.
