An air/fuel intake manifold module having fuel injectors and having an electronic engine control module (ECM) cooled by the passage of air through the manifold. The ECM is protected from contamination and damage by a coating. The ECM may be mounted in the air flow path immediately ahead of the main engine throttle body, or in a well formed in a wall of the manifold. The ECM in the well may be further cooled by placement of a heat-sink between the ECM and the manifold or by fins extended through the manifold wall into the air stream within the manifold. Alternatively, the ECM circuit board itself may be extended through a slot in the manifold wall into the air stream, or the circuits may be applied to, or formed directly on, an interior or exterior surface of the manifold. Lead wires may be cast into the manifold wall to eliminate the need for a wiring harness, such that control circuits are automatically formed when the fuel injectors and ECM are installed onto the manifold, thus forming an integrated air/fuel manifold module.
