yeah.. just know that if you go copper then they run a little cooler and yes you do have to change them more often .. but when i drive i go for straight up performance.. changing plugs every ten thousand miles doesnt bother me... and yes keep the gap on the small side to lessen the chance of misfire...

 

You notice any improvements in MPG with the copper plugs?

 

i havent tried the laser platiums but with it chipped i get 17.5 mpg around town.. and i drive hard evvvvvvvery time.. ill get over 22 on the highway...
