LMSI-G35X

Just did my plugs at 53k. I did an EPL stage 1 tune and it was recommended and it was time anyway so I bought the recommended plugs, gapped them and installed them tonight. Maybe one of the easiest things I've done on the car. Only thing that's a pain is I did drain the coolant expansion tank and remove it so I had easy access to the drivers side. I can't imagine doing it otherwise. I did notice very little oil on the plugs on the drivers side (bank 2) I think. Something to be concerned about? I didn't notice it on the passenger side at all. Thanks to everyone who's posted a DIY and other tips they all came in handy and work.

My 3.0 i did the plugs recently myself and i had no oil in any of oil wells. I do drive a bit hard in the summer. I am using motul oil and change oil between 5000 - 6000 miles. I changed plugs at ~49500 miles.
