So did you notice an improvement in performance after replacing the plugs? I’m almost at 60,000 miles of hard use, now with a few mods including downpipe, intercooler, Polestar time and TDI Tuning box on top of that, on my T6 3.0T. I’m considering replacing my plugs a little earlier than scheduled maintenance recommends (which I think is scheduled for the 70,000 mark). My car runs fine at present but I wonder if it would be worth the effort to replace them a little early given my modifications and aggressive driving habits.
