Technical Details and Specifications

The Wix 51261 oil filter is classified as Hb with a heavy-duty duty type, making it suitable for demanding engine environments. Its enhanced cellulose media provides a BetaRatio of 2/20=30/41, ensuring efficient particle retention while maintaining optimal oil flow. The filter’s bypass relief valve is set at 19 psi, allowing oil to bypass the filter element if it becomes clogged, preventing engine starvation. With a burst pressure of 350 psi, this filter withstands high-pressure conditions without failure. The spin-on design simplifies replacement, and the closed inner diameter top ensures a secure seal. The filter’s dimensions and thread size are engineered for compatibility with specific vehicle models requiring a 1-12 thread size.
