I am searching for an original spark plug replacement number. I was told the wrong one and after installing it my fuel mileage has gotten worse. I have misplaced my manual. It is not a supercharged model. They are iridium plugs and are more expensive, but they are worth the cost when it comes to fuel savings. Where can I look or go in order to find the proper replacement number?
