The OEM PF66 filter comes up short with 133 square inches of filter media with a 25-30 micron filtration rating. The simple leaf spring design to secure the oil seal loses tension and can lead to dirty oil blow-by. It also doesn't come with an integrated magnet to help protect your engine from ferrous metal particles.

The PPE upgrade has superior filtration down to 10 microns and 188 square inches which equates to 41 percent more specially engineered media than the stock filter. A perforated metal center core provides media support. Blow-by is eliminated by a stiff coil spring for a tight seal.

This filter upgrade also includes an integrated magnet to catch ferrous metals, a silicone anti-drain-back valve prevents dry starts, and a 30 percent thicker base plate features 29 percent larger passages for higher flow.
