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?
- Need help? Call 1-800-FilterMag or use the Contact Us form.
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.
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
- Measure the outside diameter (O.D.) of your filter, or
- Search for your filter’s outside diameter (O.D.) at any filter manufacturer’s website.
