I have had Bosch Platinum 4s since 64000 miles. I now have 105000 miles and I haven't had a single problem with the plugs.

The previous owner of my Ranger had just put Bosch plugs in it when I bought it. Very shortly, it developed misfires, which was corrected by installing Motorcraft double platinums.
