copper ngk plug life question?
Ive got a set of copper NGK plugs in my 03 GT and ive had them for a year and half or so probably 12-15k the car doesnt feel quite as responsive as it did before so im thinking it could use a tune up how long do copper plugs last?

k thanks thats what my dad was saying i ran some seafoam through it tonight and it seems much more responsive and i put a can in the gas tank as well. Its been a while since i had ran it through the car but it seemed to help.
