Every time you start up your engine, your spark plugs have to withstand extreme pressure and heat inside of the cylinder. As a result, they need to be designed to prevent fuel additives from building up on them. If your engine consistently misfires or your car is hard to start, it's probably time for a new set of Eclipse performance spark plugs.
