I have roughly 19,800 miles now, and around 22 total trackdays on the car. Doing very well. Today I was at the dealer for a scheduled oil change and the computer indicated that I needed new spark plugs, which they did under maintenance/warranty. SA mentioned that it's early to need new plugs, but it makes sense given the track use, and the plugs looked like they needed to be changed. Anyone else change their plugs early?
