AMSOIL EaHD Heavy-Duty Oil Filters provide high-efficiency filtration and high contaminant capacity for heavy-duty on- and off-road diesel and gasoline applications. Premium full-synthetic filter media captures and holds small, wear-causing contaminants while maintaining excellent oil flow throughout extended service intervals.

98.7% Efficiency at 20 Microns

AMSOIL EaHD Heavy-Duty Oil Filters provide 98.7 percent filtering efficiency at 20 microns in accordance with industry-standard ISO 4548-12. Increased filtration efficiency helps remove small, wear-causing contaminants before they can circulate throughout the engine.

High-Efficiency Full-Synthetic Media

EaHD Heavy-Duty Oil Filters use premium-grade full-synthetic media engineered for high efficiency, contaminant capacity and durability. The resin-free synthetic media incorporates wire-screen backing for additional strength and accurate filter construction.

Excellent Oil Flow

The small synthetic fibres used in EaHD filters trap fine particles and hold high levels of contamination while providing better flow than conventional cellulose filter media. Lower restriction is particularly beneficial during cold-temperature warm-up, helping oil circulate through the engine more quickly.

High Contaminant Capacity

EaHD Heavy-Duty Oil Filters provide high holding capacity for wear-causing contaminants. This combination of filtration efficiency, capacity and oil flow makes them well suited to demanding heavy-duty applications and extended service intervals.

Heavy-Duty Construction

EaHD filters are engineered for demanding service using premium construction and durable sealing materials. Depending on the individual filter design and OEM requirements, construction features include wire-backed full-synthetic media, heavy-duty baseplates, stamped end caps, louvered centre tubes, moulded element seals, roll-formed threads and long-life HNBR gaskets.
