At 10,000-20,000 rpm, clean oil matters.
Your oil filter cannot capture the sub 20
micron particles that cause the most engine damage.* Modern engines have tighter machining tolerances than those of the 1970s, when ISO filtration standards were developed.
How Bear Trap Magnetic Filters Work
<clearance under load diagram>
A used oil filter showing particles captured by the Bear Trap™ Magnetic Filter Pad.
Bear Trap™ magnetic filter pads buddy up with your filter to extend the life of your engine by trapping even sub micron particles as shown above.
The Bear Trap™ Flex-Fit design and powerful rare earth magnet configuration penetrate deep into your filter to trap and hold damaging particles. It snaps on instantly and slides easily into the tightest spaces.
The Bear Trap™can be reused over and over, with a proven life of over 15 years.
