My wife has a 2016 Accord and I have a 2017 Accord coupe. Both cars are V6s. The dealership just quoted her $450 for 60k spark plug change. That's olny for labor and plugs. I am just shocked to see them ask for so much. I was expecting something like $275ish (180parts+labor). Changing plugs on a J-series is very very easy. It took less than 30mins to do my own.
