• Built to OEM size
• Fits precisely in your ride
• Improved epoxy
• Uses high temperature epoxy that is stronger than OEM, eliminating the possibility of magnet detachment.
• High grade steel capping 
• Prevents harsh additives in motor oil from degrading the epoxy attaching the magnets. Though extremely unlikely, if a magnet did ever come loose, it would remain in the sleeve preventing contact with the stator.
• Eliminates crankshaft vibrations for longer engine longevity.
