Funny,
On my old N52 I changed the plugs at 100k and then at 190k both times the old plugs looked good and the engine response stayed the same. I'm was tuned and did the tuning myself, pretty sure I'd notice a performance difference with the new plugs.
Never had a coil fail.
My commute was 75% freeway at good speeds. Kombi would say my average was 50 MPH.
I've moved and my new average is 25 MPH😢. But now I'm 4.5 miles from the office instead of 43. Makes me wonder what I'm doing with a tuned Z4 35IS,
