Cartridge Filters

FilterMags work great on aluminum and plastic filter housings.

If your car or truck doesn’t have have a spin-on filter, you still may be able to provide maximum protection for your engine. But you’ll have to do a bit of research.

To determine if a FilterMag can fit your application,
follow these steps.

Is there space for two FilterMags, or only room for one?
How much smooth, clear vertical height is available on the housing?
What is the diameter of the outside of the housing? This will determine which size FilterMag to buy.
What diameter band clamp will you need?

Installation on Plastic or Aluminum Cartridge Filter Housings

Install two FilterMags with a band clamp on the housing opposite each other near the threaded end. Wear safety glasses.
The FilterMags need to be firmly secured to the housing, but don’t over tighten.

How to change the filter.

Remove the FilterMag if necessary for clearance.
Remove the cartridge housing, and clean out the particles trapped by the FilterMag.
Replace the filter and replace and tighten the cartridge housing according to the manufacturer’s instructions.
Reinstall the FilterMag.

There may be space below the plastic filter cover to attach a pair of FilterMags to the aluminum filter support.

How to Select the Correct FilterMag for Cartridge 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.
