CHI's water-crossover / bypass housing is the perfect accessory for our new range of inlet manifolds, allowing you to easily convert your 8.2" & 9.5" deck Windsor engines into an all conquering BOSS power plant. Designed to replace the integral water passage and thermostat housing used on Windsor intake manifolds, our water crossover redirects the water out of the front of your CHI, Cleveland & Yates Cylinder heads, and conveniently relocates the thermostat housing horizontally above the original Windsor position.
