It's not starting seriously slow but I notice it turning over a bit longer than normal. Sometimes the start is ..crisp.

109k miles.

No other issues. Shifting hard yet smooth like it should.

Could this be an indication I need spark plugs replaced?

I dont imagine it real serious ..just a tad too slow at times.

If it was turning over slowly, I would look at the battery first and starter second.

Get your battery on a battery charger and when it is fully charged take the vehicle to the auto parts store and ask them to check the battery, alternator and starter. They usually do this for free.

And addition to the other great replies here that may actually solve the problem, if you still have the original plugs at over 100K, it may indeed be time to replace them.

Sounds like a number of small items more than likely and nothing major. Correct?

One thing I don't have in the garage, among many others, is a battery charger. New batter wouldn't hurt at 100k right? No clue how long they last TBH.

OEM Denso? Was looking at thier racing option...

I jumped feet first int this community like some of you may have. Seems like a good website community for ..my G37.

I plan to just keep this and reso it completely. It's licking the wounds on a car deal yes but I see things balancing evenly in the end. Wife gets it until about 170k then it will become my personal winter car.

My other machine is a 2011 Challenger SRT8 and it is, to my astonishment, getting no attention right now. Hahaha

Is it easy to replace the spark plugs yourself?

Replaced with Autolite's iridium plugs for $44.

No big change and nothing weaker.
