Mobile mechanic advertising on Craigslist has quoted me $120.00 labor to change the plugs on my 2012. Not sure he is up the the job. First question he asked is the engine "Inline or Straight" Not sure I want him working on my truck, I may be able to handle the job myself just worried about snapping a plug off or cross threading one. Opinions please, I need to do this next weekend as I got JDM tune coming in shortly.
