The new design oil filter cap can be identified by the rounded contour of the outer edges, rather than the flat edges on the previous designs. This new design oil filter cap is intended to backservice all previous model year vehicles. The new design oil filter element must be used to service vehicles with this new design oil filter cap. Refer to the "Parts Compatibility" table included in this bulletin for more information.

Notice: Do NOT use an old design oil filter element (P/N 22685727) in combination with the new design oil filter cap . The bypass valve in the new design oil filter cap is designed with increased relief pressure. Use of an old design oil filter element with the new design oil filter cap could result in damage to the engine.
