Abstract
A system for a cylinder head is provided. The system comprises a cam cover mounted on the cylinder head and including an oil separator and a coil on plug (COP) coupled to the oil separator via a snap-fit connection. The snap-fit connection holds the coil-on-plug in position and may provide a lower cost alternative to existing systems of retaining coil-on-plugs on a cam cover.
