Query: Failed After 2 Years and 15K Miles

Bought this Bosch plug wire set in October 2007 and put on my '98 Camry with 62K miles (along with new platinum spark plugs).Just turned 77K miles in December 2009 and picked up a 'Random Misfire - Cylinder #3' code. After troubleshooting, found that the misfiring cylinder changed upon swapping plug wires, confirming that one of these Bosch plug wires had failed. Totally unacceptable after only 2 years and less than 15,000 miles of use.Pay a few more dollars up front and get the NGK plug wires that Amazon also sells...wish I had the first time around...(BTW, good luck with the Bosch 'lifetime warranty'. Just try going to the Bosch site and finding any info about how to make a warranty claim. Not worth the little scrap of paper in the box it's printed on!)
