A combustion air inflow path, for a vehicle heater, includes a bottom area (24) and an outer circumferential wall (26) adjoining the bottom area (24) and extending essentially in the direction of a central longitudinal axis (L) of the inflow element (22). An inner circumferential wall (32) is arranged at a radially spaced location from the outer circumferential wall (26) and defines a space area (52) with same. An inflow opening arrangement (38) is provided for the inflow of air into the inflow element (22). The inflow opening arrangement (38) is provided in the bottom area (24) and is designed to generate a turbulent flow.
