Abstract
An air heater for heating intake air for an internal combustion engine only in cold start or further warming up operation, having a frame which defines an opening for passing air therethrough, and at least one heater element in the shape of a perforated plate such as a lattice or honeycomb plate supported by the frame so as to traverse only a part of the opening area of the air passage opening, while leaving a substantial part of the opening area free as untraversed by the heater element.
