This might be a silly question, but.. i have a 2008 g37s coupe with minor mods such as cai & test pipes. and was wondering what spark plugs i should get for my tune up or what spark plugs other G owners get. thanks for any feedback!

 

i do believe that the spark plugs are already iridium. and those are "supposed" to last forever.

from what i gather, changing the spark plugs on the 3.7 sucks monkey ballz

 

HKS FTW. but kind of overkill unless you're getting tuned

 

Spark plugs are good for 100K.

 

I just replaced my plugs and cleaned my throttle bodies on my 09 s with close to 60k, and it feels a bit stronger. The gap on the old & new plugs was no where near the 1.1mm they call for, so I carefully regapped them to specs. Only took about an hour or so to do, and fairly easy..

 

what spark plugs did u use?

 

The OEM denso plugs-FXE24HR11

 

i think if i were to change the plugs, i'd end up going with a cooler burning plug. they're a little more efficiant.
