Designed for modern engines, our MANN OIL FILTER products have excellent dirt-retention capacity thanks to clever design of the filter elements. Our reliable spin-on oil filters offer smooth handling and high-class performance. The return stop valve (which ensures your filter and oil channels don’t completely empty when your engine is turned off) keeps your oil ready to flow as soon as you switch on the engine. In cold conditions the bypass valve is essential to making sure your car starts. Cool temperatures can make oil thick and sticky. This valve keeps up lubrication, before switching to filtered oil once the engine has warmed up. Every filter is built to provide clean oil to your engine. Due to the wide range of applications and varying requirements, MANN-FILTER offers oil filters in different design types to meet specific needs
