关于换火花塞，这里说

"According to CarMD, replacing a spark plug on your own can cost less than $10. However, because faulty spark plugs can reduce your gas mileage or melt your car’s significantly more expensive catalytic converter, having them replaced by a certified mechanic may actually be worth the added expense. "

我这才自己换了，是在advanced auto parts 买的，bosch. 应该没事儿？
