The ECOGARD X11646 Oil Filter is engineered to provide exceptional engine protection for a wide range of commercial vehicles, including the 2025 Chevrolet LCF series, Isuzu ELF and Forward series, and Hino S4 and S5 models. Designed to meet OEM specifications, this filter ensures optimal performance and longevity for diesel engines. Its high-efficiency filtration system captures particles as small as 30 microns, safeguarding engine components from abrasive contaminants. The one-piece spiral wound, corrugated center tube enhances collapse strength, while the molded nitrile anti-drain back valve prevents dry starts, ensuring immediate oil circulation upon engine startup. The pressure relief valve maintains consistent engine lubrication, and the heavy-duty filter body withstands five times the normal oil pressure, providing durability under demanding conditions. The precision-forged threads on the heavy-duty baseplate ensure a secure and leak-free fit. With a height of 4.72 inches and an outer diameter of 4.8 inches, the X11646 is compatible with various vehicle models, including the 2025 Chevrolet LCF 4500HD, 5500HD, 5500HG, 5500XD, 6500XD, Isuzu ELF 400, 500, 600, 600-BUS, Forward 1100, 800, FTR, NPR-HD, NPR-XD, NQR, NRR, and Hino S4 and S5. This filter supersedes the previous X10249 model, offering enhanced performance and compatibility for newer vehicle applications.
