Just don't use Bosch Platinums, I have had to change my plugs twice, and this will be the third time. 1st time I use Bosch double tip plats, very bad idea, then I tried single tip bosch plats, gapped to SVT specs, better, but now they have gone bad as well.... I know other guys with these issues as well.
