LS Stainless Coolant Crossover For LS1, LS2, LS3, LS6, LS7, LS9

LS Stainless Coolant Crossover Steel Steam Vent KitStainless Steel Steam Vent System connects the 4 corners of your LS engine to remove trapped steam and get it where it needs to go. Steam / Built Up Pressure creates elevated temperatures.  The LS engine has 4 corners for a reason and we suggest connecting them on ALL modified engines using whatever means are possible. When steam gets trapped pressures rise, when pressures rise it creates an unsafe tune condition which can lead to pre-detonation, head gasket failures, lean cylinders causing piston failure etc.This system has proven itself time and time again in the real world with our customers. Adding this and our other style of steam vents have taken problematic combos where #8 and 7 cylinders were having gasket or lean issues and cures them.It not only works well but looks amazing as well. This setup combines CNC aluminum manifold and corner ports with 304 stainless steel line. Each kit is hand built. Aluminum blocks are offered in
