Mobil 1 Extended Perform ance Oil Filter M1-403A

The Mobil 1 Extended Performance Oil Filter M1-403A is engineered for drivers and mechanics who demand reliable engine protection without frequent service intervals. Built to deliver extended drain capability, this filter is designed for modern vehicles that benefit from synthetic or synthetic-blend oil formulations. Whether you're maintaining a daily driver, performance build, or fleet vehicle, the M1-403A bridges the gap between OEM efficiency and aftermarket durability, reducing maintenance frequency while safeguarding critical engine components.

This filter leverages advanced media technology and reinforced construction to trap contaminants—sludge, dirt, and wear particles—that accumulate during extended service periods. The M1-403A features a robust bypass valve and anti-drainback design that maintains oil pressure immediately upon cold starts, preventing dry-cranking damage to bearings and valve trains. At 1.52 lbs and measuring 4 x 3.95 x 7.4 inches, the compact form factor ensures clearance in tight engine bays while providing superior filtration efficiency compared to basic spin-on alternatives. The extended performance rating allows for longer intervals between replacements when paired with quality full-synthetic oils, reducing labor costs and downtime in both street and track applications.

The M1-403A is ideal for vehicle owners and independent shops seeking OEM-equivalent or superior protection across GM, Ford, Chrysler, and foreign nameplates that specify M1-403A or equivalent fitment. Mechanics upgrading from standard filters will notice improved oil flow characteristics and reduced pressure drops during high-RPM operation—critical for forced-induction or modified engines. Installation requires no special tools; the spin-on design accepts standard filter wrenches and hand-tightening. For those running extended drain intervals or synthetic oil schedules, this filter provides confidence that engine internals remain protected through extended service cycles, making it a cost-effective choice for both preventive maintenance and performance-oriented builds.
