So then whats the gain in changing your plugs 4x every 60k miles ( copper) rather than only 1x every 60k (iridium)?
The reason I go with the coppers is because I only put about 5k miles on the car in a year and since I'm am modding fairly often I don't see the point in buying a 60k plug.
Get it tunned when i bought my evo 8 i was getting 200 miles out of a gas tank and after the tune i get 300 miles on a gas tank and thats using the boost preaty often.
