MicroPure XR® Engine Oil Filter - Replaces AC Delco PF47, PF52, Motorcraft FL-321

Engine Oil Filter - Replaces AC Delco PF47, PF52, Motorcraft FL-321

The oil filter is your engine’s first line of defense against contaminants that degrade oil performance and reduce oil lifespan. Poor filter performance and the presence of oil contaminants can lead to premature wear and potential failure of engine internals. The OEM filter falls short, offering only 20-micron filtration capability and using a weak leaf spring, allowing dirty unfiltered oil to bypass.

PPE’s upgraded filter provides 218 square inches of filtration area, a massive 122% increase over the OEM filter. The specially engineered ultra-fine synthetic blend MicroPure® media achieves a 10-micron nominal rating. An integrated high-temperature rated neodymium magnet also allows the PPE filter to capture ferrous particles, preventing them from clogging the media, extending filter and oil life. The use of a heavy-duty coil spring ensures a secure seal between the media end cap and the base plate, eliminating dirty oil blow-by and maximizing filtration performance. The PPE filter also features a heat-resistant silicone anti-drainback valve, retaining oil in the filter after the engine is turned off for dry-start protection.

The PPE filter’s heavy-duty construction, consisting of a high-strength steel base plate a durable metal center tube, allows for superior media support and pressure resistance. The filter cannister is also thickened to minimize deformation under pressure, achieving a remarkable 350+ PSI burst pressure.
