Abstract
A compression limiter formed by a roll forming process includes a substantially cylindrical body portion and a plurality of feet. A plurality of notches are stamped along a lower edge of a flat sheet of stock and bent to form the plurality of feet. The flat sheet of stock is then rolled to form the compression limiter. In the preferred embodiment, the compression limiter is formed of a high carbon steel. The plurality of feet of the compression limiter transmit the bolt load of a fastener attaching a plastic intake manifold to a component. In an alternative embodiment, an angled portion attaches each foot to the body of the compression limiter which accommodates for variations in the height of the plastic intake manifold.
