COOLANT CAPS ia a revolutionary new product known as a HEAT TRANSFER ENHANCER. This product changes the infra-red conductivity of coolant to enable the coolant to conduct infra-red more rapidly in both radiation and absorption situations. For example, in a racing engine application cooled by water, the enhanced coolant will absorb more heat from exhaust port to water, combustion chamber to water, and cylinder to water, because the infra-red (heat) is absorbed more quickly into the water with the heat transfer enhancer added (compared to water without the additive). When the absorbed heat trapped in the water is moved to the radiator, the infra-red (heat) is conducted more quickly into the radiator tubes.
