    KRC's one inch thick thermostat housing spacer is machined to accept a thermostat and has two 3/8" NPT threaded holes. These holes are designed so you can run hoses from the spacer to two points on the back of the intake manifold. This helps eliminate hot spots in cylinder heads and engine blocks.
