I bought 4 NGK iridium type spark plugs at my neighborhood auto zone.
The explanation from the guy was that as small is the spark tip, the better is the spark and less fuel it will burn, saving gas. They cost $7.80 each.
I am not sure if it is what he said. I already installed. I felt a very little difference on performance.
What do you guys think about that ? Is there any good spark plug out there better or is this one a decent one ?
