The originals are ceramic and they last a very long time.
I changed my rears at 65K, 136K, and 198K.
I changed the fronts at 80K, and 160K.
The originals were always replaced with good aftermarket ceramic pads which seem just as good as the OEM's. Don't go with cheaper semi-metalic, always use ceramic pads. They cost over $100 per axle, but they're well worth it. They also don't leave any visible brake dust.
