AFE D2 ProGuard Oil Filters 1994-2003

Most particles larger than 40 microns are trapped by air filters or cannot pass by an engine's piston rings and enter the oil system. Particles smaller than 5 microns pass through an engine without causing damage. It's the particles between 5 and 40 microns that penetrate a vehicles defense, contaminate engine oil, and ultimately cause destruction. aFe Pro Guard D2 oil filters with NF21 full-synthetic media trap these particles without sacrificing critical oil flow for the ultimate engine protection.
Please also consider, where applicable, AFE intake systems, fuel and transmission filters.
