WIX Racing Filters 51040XP XP Full-Flow Spin-On Engine Oil Filter

The WIX Racing Filters 51040XP is an XP Spin-On Oil Filter for Synthetic Oil, a full-flow spin-on engine oil filter built to protect engines running synthetic motor oil in demanding conditions such as towing, extended idling, climbing mountain grades in lower gears, and long periods at highway speeds.

Key Features:

• Extended-interval ready: WIX XP filters are recommended for OEM oil and filter change intervals, typically 3,750 to 10,000 miles.
• High dirt-holding capacity: Traps up to 100% more dirt and contaminants than the standard WIX filter, helping resist premature plugging as oil breaks down.
• Fully synthetic media: Withstands harsh oil temperatures and operating conditions.
• HNBR gasket: A specially formulated gasket that seals well during extreme cold starts and resists hardening at elevated oil temperatures.
• Silicone anti-drain back valve (when applicable): Helps protect against dry starts, even beyond the traditional filter change interval.

Oil filter laboratory test performance for the XP line is per ISO 4548-12: 32 grams of dirt capacity (tested on 51515XP) and 99% efficiency at 35 microns (based on 51515XP, 51356XP and 57060XP).

A dependable choice for owners who run synthetic oil and want added filtration protection for severe-duty driving.
