The "Triad Fibers" technology period didn't last a long time. Fram air filters included Triad Fiber technology for a period as well. I recall issues with rogue fibers dislodging and melting on MAF sensors being an issue with the Fram Triad Fibers air filters. Fortunately I've never owned a vehicle with a MAF sensor.
