Abstract: An improved oil filter, for use with an internal combustion engine, comprises a hollow filter housing defining a chamber therein and having an inlet and an outlet with a flow path therebetween; a mechanically active filter member disposed inside the filter housing in the flow path; and a chemically active filter member disposed inside the filter housing in the flow path. The chemically active filter member comprises a plurality of composite oil additive pellets. The plurality of pellets is interconnected to form a substantially integral permeable member, and the substantially integral permeable member is impregnated with an alkaline composition. The alkaline composition is provided to counteract acidic combustion products in lubricating oil in an internal combustion engine.

Abstract: A spark plug is provided. The spark plug has an insulative sleeve with a central axial bore and an exterior surface of a shaped tip portion. A coating is disposed on the exterior surface of the shaped tip portion and the coating comprises a transition metal compound or a combination of transition metal compounds, and an alkali metal compound. A center electrode extends through the central axial bore of the insulative sleeve. A metal sleeve is provided, wherein the insulating sleeve is positioned within, and secured to the metal shell. A ground electrode is coupled to the metal shell and positioned in a spaced relationship relative to the center electrode so as to define a spark gap.
