Always confirm fitment and specification before purchase. How to use this cross-reference If you already run a WIX racing filter, find its number in the left column to see every competitor part it replaces. If you are coming from another brand, type your current part number into the search box and the matching WIX filter will surface. The search reads the WIX number, the competitor parts and the brand names together, so a partial entry like "512" or "moroso" narrows the list as you type. What the WIX part numbers tell you WIX racing filter numbers carry an R suffix to mark them as part of the racing range. A bypass valve, noted in the final column, lets oil keep circulating if the filter media becomes restricted, which matters in high-output and cold-start racing conditions. Where a competitor filter cross-references to more than one WIX number, such as the Fram HP6 to either 51222R or 57003R, choose based on availability and your specific application. The cross-reference is a fitment guide only. As WIX states, competitors' products are not considered equivalent to WIX's products, so confirm the specification suits your application before fitting.
