Detailed Product Description

WIX 51365 is engineered for vehicles that call for a compact spin-on filter with OE-style service characteristics. It is listed for applications such as 2000-2013 Subaru Legacy, 1999-2005 Mazda Miata, and 2000-2006 Honda Insight, along with additional Mazda 2, Subaru Forester, and Subaru Impreza coverage. The filter media is designed to capture contaminants while maintaining flow, and the anti-drainback valve helps keep oil in the filter when the engine is off.

This part cross-references FRAM PH6607 and Purolator L 14612 for the same application.

What This Filter Helps Address

• Oil contamination from normal engine wear
• Dry-start noise after extended shutdown
• Reduced filtration performance during severe driving cycles
• Service replacement needs at OE-recommended intervals
• Fitment matching for Mazda Miata, Subaru Forester, and Honda Insight applications

Installation Notes and Tips

Verify the thread size, gasket sealing surface, and overall dimensions before installation. This filter uses a 20x1.5 mm thread and a closed top configuration, so it should be matched to the vehicle’s specified filter type. Follow the manufacturer’s oil change interval and confirm the application against the vehicle’s engine code or OE part number when servicing Mazda 2, Subaru Tribeca, or Ford Escort models.

Quality Assurance

WIX specifies this filter for OE vehicle manufacturer oil and filter change intervals and severe-duty driving conditions. Laboratory performance data cited by WIX includes dirt-holding and efficiency testing under ISO 4548-12 methods.
