AMSOIL Ea Heavy Duty Oil Filters

Ea Heavy Duty Oil Filter

Absolute Efficiency

Efficiency refers to a filter's ability to trap wear-causing contaminants and prevent them from circulating throughout the engine. Ea Heavy-Duty Extended-Life Oil Filters are engineered using full-synthetic media that provides a filtering efficiency of 98.7 percent at 20 microns in accordance with industry standard ISO 4548-12, ranking them among the most efficient available for heavy-duty applications. Increased efficiency helps reduce wear for long engine life. Reference AMSOIL Heavy-Duty Bypass Systems for even more contaminant-removing 

Less Restriction

Ea Heavy-Duty Oil Filters have lower restriction than conventional cellulose media filters. Their small synthetic fibers trap smaller particles and hold more contaminants, while providing better flow than cellulose media. During cold-temperature warm-up periods, an Ea Heavy-Duty Oil Filter allows the oil to flow through the filter more easily than a typical cellulose filter. Lower restriction helps circulate oil more quickly, promoting long engine life.

Contaminant Capacity

A filter's capacity refers to the amount of contaminants it can hold and still remain operational. AMSOIL Ea Heavy-Duty Oil Filters have a high holding capacity for wear-causing contaminants.
  • Increased efficiency compared to cellulose filters for maximum wear protection
  • Extended service intervals increase convenience and reduce maintenance
  • Full-synthetic media
