Thermal spacers lift the intake manifold off the super heated engine to lessen the transfer of heat. Both the intake manifold and engine block are aluminum so the high heat transfers very quickly....well these spacers stop that. The cooler the intake charge the more HP and TQ your engine will make. In addition to cooling your intake charge, these will also give you larger intake volume similar to that of a throttle body spacer.
