1) no, it's not a 2-hour job. Last time I changed plugs it was on my 6 cylinder car, it took me 30 minutes, and that was first time on this vehicle with harder-to access plugs. This 4-cylinder engine has easy access to its plugs.

2) I watched the YouTube video on this exact car doing this job. The video didn't have breaks/edits the total video runtime was 28 minutes, and included some explanation time.

3) I Googled for repair costs for this job on this vehicle. The cost range is $154 to $247. The place my daughter went to wanted to charge $200 more than the high end of that range.

Having done this job myself on a few different vehicles, I still say it's a 25 minute job for a professional. Others in the thread who have done it agree with me.
