Been a while since I have been on, apologies!
My 2002 s8 has 170K on it and was running Bosch super 4's when I bought it at 120K. It was converted at 60K so has over 110K on LPG. I switched to iridium at my second service (130K), LPG specials and they resulted in lumpy running after only about 15K miles (diagnostic check showed misfire, swapped plugs and coils, turned out to be plugs)
Put them in the bin and went back to bosch, never missed a beat since.
I can look out the exact reference if you are still looking. I don't make a habit of dissing products online but those iridium ones were expensive rubbish, In fact I was away camping at the time and put the old bosch ones back in and it solved the problem, then replaced them with new bosch when I got home.
