-14- Abstract of the Disclosure A plate mounted between the carburetor and intake manifold having horizontally extending passageways and inlet and outlet ports communicating with four vertical apertures aligned with the passageways of the carburetor and intake manifold. Double-walled tubular heat exchangers, formed of spaced apart outer and inner jackets, are disposed in the vertical apertures, the spaces between the outer and inner jackets communicating with the plate passageways and being sealed from the inside of the inner jackets, such that engine coolant can be circulated through such spaces and through the plate to cause pre-heating of the fuel-air mixture as it passes through the inside of the exchangers and into the intake manifold. The inner periphery of each inner jacket has ring shaped serrations and a downward taper, which,together with pre-heating by the heat exchangers, results in significantly improved vaporization of the fuel-air mixture.
