I have been running Denso Iridiums for 125k and not had one fall apart yet. Wrecked a set of NGK in record time and find the Denso run for more than 50k a set so happy with them. But don't get them from tuners, ebay has great prices if you look on it enough

yes on one Z20 and a 1,8T vag along with a few cosworths
all down to how the car is used
the audi was at 115mph not giving a hard time just driving home at 2am on a empty A12 for 10mins an one of his plugs let go

the vauxhall was this year on the way home from PV
he was on the motor way at 70ish an it just let go an killed its engine
had to fit a new engine on that
