How often do you change your spark plugs?
I just did the 60k oil change. According to the scheduled maintenance it states to change spark plugs every [EDIT] 30k for emissions warranty. I'm not worried about that.
I've yet to change the plugs on my Tundra.
I have a 100 mile roundtrip off-peak daily commute, so most of my miles are highway miles at low revs. I do haul and tow occasionally, and also put a few miles off road on the ranch, occasionally in 4WD low.
So, time to change them? If so, anyone recommend a good brand?
