Hello, I have a 08 Sedan(it's really my ol' lady's car) and for what ever reason it likes to "eat" it's #1 plug. I used to use E3's until the car ate the first one and the center electrode nearly fell into the combustion chamber then two set's of Bosch Iridiums and both times the ground strap was missing. It does this and the only time it misfired was with the E3. I'm at a loss. Is this normal or do I have bad luck with plugs?
