An injection plate assembly for an internal combustion engine that includes a manifold and carburetor or throttle body is provided for injection of a primary fuel and an accelerant into throttle bore(s) of the manifold. The injection plate assembly is adapted to be installed between the manifold and the carburetor. In order to equalize injection of both the primary fuel and the accelerant, the lower plate includes at least two fuel inlet ports that provide fuel at opposing sides of the lower plate. The upper plate includes at least two accelerant or additive inlet ports that provide accelerant to opposite sides of the upper plate, with the accelerant inlet ports being located on different sides of the injection plate assembly from the fuel inlet ports on the lower plate. To further improve flow of the accelerant to the injection gates in the upper plate, the runners in the upper plate define paths that have internal corners having a radius of 0.10 inches or greater. This ensures less head loss for the high pressure accelerant as it is delivered via the runners to the injection gates which normalizes the accelerant delivery from the injection gates at all sides of the main apertures.
