Detailed Description

WIX 51225 is engineered as an engine oil filter for applications that call for a compact spin-on design with conventional filtration media. The filter’s cellulose construction supports routine oil changes with conventional, synthetic, or synthetic-blended motor oils when those oils are specified by the OE vehicle manufacturer. Its bypass relief setting helps maintain oil circulation if the media becomes restricted, while the steel canister, center tube, and end caps are built for corrosion resistance and sealing integrity under normal service conditions.
