Fleetguard LF03664 00MX Oil Filter

LF03664 00MX is a high-efficiency spin-on oil filter engineered for Cummins ISB 4.5L/6.7L medium-duty diesel engines, ideal for medium-haul freight trucks, refrigerated transport vehicles and municipal maintenance machinery. It adopts premium StrataPore® dual-layer filter media, delivering 99% filtration efficiency at 32 microns, effectively trapping metal particles, carbon deposits and oil sludge to protect engine bearings and piston rings from premature wear.
With a stable flow rate of 32L/min, it maintains optimal oil pressure during continuous medium-load operations. The filter features standardized dimensions: 92mm outer diameter, 172mm height, and 1-14 UN-2B thread specification, ensuring seamless fit with original mounting positions.
As an OEM-grade replacement for part numbers 3935641 and LF3664, it supports tool-free installation and performs reliably in variable temperature and dusty working environments, making it a cost-effective choice for medium-duty equipment fleets.
