So the other day I was going to change the plugs in my Alero and when I took the plugs out they weren't the factory plugs. They were a E3 diamond fire plug. I've heard of these before and how they are "suppose" to help you get better gas mileage. The previous owner put these in. Was wondering what other people knew or thought about these. Should I leave them in or get different plugs. If i should get different ones, which ones should I get?
