Detailed Description

WIX designs this oil filter for OEM-style maintenance intervals, typically 3,750 to 10,000 miles and not beyond 12 months, depending on the vehicle manufacturer’s service schedule. The filter is intended for normal and severe driving conditions, including stop-and-go traffic, dirt roads, construction sites, short trips, and highway travel. In laboratory testing referenced by the manufacturer, the filter media is engineered to trap more dirt and contaminants than Protec in severe-duty use cases.

For fitment-based searches, this part is commonly referenced for Fits 1990-1995 Chevrolet Corvette, N/A; Fits 1984-1987 Ford Escort, N/A; and Fits 1984-1987 Mercury Lynx, N/A. It also appears in applications for Fits 1984-1986 Ford Tempo, N/A and Fits 1984-1986 Mercury Topaz, N/A. The WIX 51324 is also cross-referenced with NAPA Gold Filters 1324 for the same application.

What It Helps Address

• Engine wear caused by dirty oil circulation
• Oil pressure loss at startup after extended shutdown
• Contaminant buildup during short-trip or stop-and-go driving
• Reduced filtration performance during severe service intervals
• Maintenance needs on vehicles requiring a 20x1.5 mm spin-on oil filter

Installation Notes and Tips

Verify thread size, gasket sealing surface, and overall dimensions before installation. This filter measures 4.354 inches tall with a 3.663-inch outer diameter and uses a 20x1.5 mm thread. Follow the vehicle manufacturer’s oil change interval and confirm the correct application for your engine before service. The anti-drain back valve is especially relevant on applications where the filter mounts in a position that can drain after shutdown.

Quality Assurance

WIX oil filters are engineered for OE-recommended service intervals and are built to support routine maintenance across conventional and synthetic oil applications. The manufacturer publishes performance data including a 21-micron rating, 280 psi burst pressure, and ISO laboratory test references for filtration performance.
