An insert for reinforcing a flange component and an intake manifold for an internal combustion engine in which such an insert is used. The insert (14a) is open toward a longitudinal side (17) of the cylinder head flange (13), so that a mounting bolt does not have to be pushed through the passageways (16) formed by the insert, but can be inserted from the side. This offers advantages during mounting, since the intake manifold can be pushed onto pre-mounted bolts, which are subsequently tightened to fix the intake manifold. The intake manifold and the described insert are therefore particularly suitable for cost-effective mounting in tight spaces.

1. An intake manifold for an internal combustion engine, said manifold having a mounting flange provided with at least one fastener receiving passage, and an insert made of a stiffer material than the flange disposed in said passage, wherein said passage and said insert are open toward an edge of the flange such that a fastener can be inserted into the passage from the side.2. An intake manifold according to claim 1, wherein the insert has a substantially U-shaped cross section with the open side of the U being oriented toward the edge of the flange.3. An intake manifold according to claim 1, wherein said mounting flange is a cylinder head flange.4. An intake manifold according to claim 3, wherein a plurality of intake pipes for combustion air are integrated the cylinder head flange, and wherein a plurality of said inserts are arranged along one longitudinal side of the cylinder head flange.5. A method for mounting an intake manifold to an installation site on an internal combustion engine, said manifold having a mounting flange provided with at least one fastener receiving passage, and with an insert made of a stiffer material than the flange disposed in said passage; said passage and said insert being open toward the edge of the flange such that a fastener can be inserted into the passage from the side intake manifold, said method comprising laterally pushing the intake manifold flange with the at least one open insert onto a fastener, and subsequently fixing the manifold in place with the fastener.6. A method according to claim 5, wherein said fastener is a bolt loosely pre-mounted at the installation site, and the subsequent fixing is effected by tightening the bolt after the manifold with the insert has been pushed laterally thereon.
