1. A cylinder head for an internal combustion engine comprising:
a cylinder head arrangement which has an intake port;
an injector connected to the cylinder head arrangement;
a tubular injection tube, which extends along a tube core axis into the intake port and is fluidly connected to the injector, wherein the injection tube has an injection aperture which opens into the intake port; and
an attachment element arranged on the injection tube, the attachment element having an air guiding portion formed as an air guiding disc with circular ring shape which extends perpendicular to the tube core axis, and the air guiding portion is configured to influence a flow of air in the intake port,
wherein the air guiding disc has a through-opening having a longitudinal axis coaxial to the tube core axis and having a diameter that is greater than or equal to a diameter of the injection aperture.
