How to select the right FilterMag for oil filters.

1. Choose Your Protection Level

Maximum Protection—Pair of SS or MC/MB FilterMags

Powerful Protection—Single SS or MC/MB FilterMag

Expose all of the engine oil flowing through the filter to Filtermag. This provides twice the opportunity for FilterMag to capture wear-causing particles in your oil.

A single FilterMag gives your engine powerful protection to remove wear-causing particles at a lower cost.

2. Choose your size based on
filter diameter

  1. Measure the outside diameter (O.D.) of your filter, or
  2. Search for your filter’s outside diameter (O.D.) at any filter manufacturer’s website.
    Please feel free to use the links provided in the Filter Lookup box to the right.
