An intake manifold flange system prevents leakage between joining portions of an intake manifold and a cylinder head while permitting stress relief. A flange body has an opening for receiving a distal end of the intake manifold and fastener hole openings for fixing the flange body to the cylinder head. Spaced annular grooves are arranged in an axial direction of the intake manifold. O-rings of a dimension to extend from the annular grooves and provide a pressurized contact with the distal end of an intake manifold. An annular groove is formed at a surface opposite a mounting portion of the cylinder head and an O-ring seal enables offsetting of the flange body from the cylinder head surface.
