The dealer is giving me some spiel about how it costs $550 to change the spark plugs because the intake has to come off. What does this mean? I know spark plugs shouldn’t cost more than $10/piece and the labor can’t be more than 30-45 mins max., say even an hour that’s $75-100/hr…where is the $550 figure coming from? 내가 당한게 거의 7-8년전 이야기니까… 인터넷에 나오는 이야기하고 동료 이야기 하고 얼추 맞는것 같은데요?
