        running cooler charge temps than standard cars,so why upgrade to cooler running plugs?

                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
