Magna Guard

 Magna-Guard oil filter magnet S.A.E.

For: ATV’s

Motorcycles

Automobiles

Under the best conditions and with the most meticulous maintenance, your engine will shed small metal particulates into the oil.  Dirt sticks to these particles.  Oil filters are designed to pass oil freely, therefore, a number of these small particulates and dirt pass through the filter’s porous element.  This increases friction and engine wear.  Magna Guard removes 40 times more of the harmful particulates than your oil filter.

     According to the Society of Automotive Engineers (S.A.E.), they have documented 8 to 14 times reduction in wear along with improved combustion with reduced friction giving you more miles per gallon.  S.A.E. documents a 3.7% to 5% increase in fuel economy.

     The next time you change oil in your ATV, Motorcycle or Automobile, just push Magna Guard into your oil filter and install.  Magna Guard holds itself in place.  The magnetic properties of the ceramic magnet will trap all of the harmful particulates missed by the filter.ter.

 

Fits any Brand or Model
         Only $7.95
