Good Morning G37 Forum,

I have a 2013 G37xS, bone stock, sitting in the garage at home. It's been my daily for the last couple years and I've owned a number of G's in the past. I wanted to see if I could get some recommendations for preventative maintenance. The car just clicked over 100K miles and it's been in Inifiniti's hands all the way with regular service up to this point. I recently picked up a set of swift lowering springs, I'd like to drop it a little bit. As well as a Stillen Grounding kit as it's been hanging gears recently and it makes me nervous. The cars got new Michelin tires all the way around, brakes in the last 10K miles, trans fluid flush, and Infiniti's 90K mile full service.

Generally, when cars get up to 100K I like to do the plugs, take a look at injectors, and other miscellaneous preventative maintenance. I wanted to hear what the forum thought would be some good items to check on, replace, etc... I've toyed with a variety of different cars over the years but have always daily driven my Infiniti's (2003 G35 6MT, 2008 G35 AT, and now this) so I don't wrench on them much. I'm completely open to suggestions and would love to keep this car on the road for another 50K miles without issue.

Thank you in advance and I look forward to hearing some responses!
