Napa Gold full-flow oil filters for automotive applications use arch-pleated, prescription-blended media. When new, the media with a maximized number of pleats has less than 2 psi pressure drop when filtering oil at a rate of 4 g.p.m. at normal operating temperature. This low initial restriction to oil flow protects the vital engine parts more effectively.
Some NAPA Filters full-flow filters include anti-drainback and/or filter by-pass valves. These types of filters are identical to full-flow filters, except that a by-pass valve replaces the inner element support and an anti-drainback valve has been added. The Anti-Drainback Valve prevents oil from draining out of the filter inlet holes when the engine is shut off. It also provides seal between clean and dirty oil at the upper end cap. This is necessary in applications where the oil filter is mounted in a horizontal or inverted position.
