I recently got an email about service and said oil and spark plugs, and I read somewhere every 30k miles is about right, specially if your tuned. I rather not run the risk for 100 bucks total (i'll be doing it myself)
I didnt change the spark plugs in my G37 until after 100k, and was running perfectly fine.
