When to replace spark plugs
I think most of the time there is for the valve adjustment. Either way the spark plugs and valve covers come off, so you're essentially getting new spark plugs and valve cover gaskets at the cost of parts. Definitely expensive!!
I know. Just about every shop quotes anywhere from $60-$120 around here PER NGK Iridium spark plug. I understand that shops have to pad their parts and labor to make a profit, and account for problems along the way. But a 1000%-2000% markup? Damn.

I replaced the plugs in my car in less than an hour, any shop charging more than an hour of work is a rip off. Figure plugs are $100, an hour of labor $120 for a total of about $220. That’s fair. Why not do it yourself, it’s very easy to do, even the back ones. Plenty of help on this

I was responding to gen erik, "nasty spark plug wells and coils". I have no idea how my post ended up where it did. It's been a few years since I've active on the forum. I hope this response ends up where it should.
