I never had good luck with coppers (hemi plugs or ngk's). The only thing my car liked to run was the ngk iridiums and i havent strayed since...of course it had to like the exspensive plugs
On a side note, i pulled my oil pan, balance shaft (yes i still had it), pistons, yada yada yada out and found that it wasnt nessesarily my piston rings that were causing me to burn oil. It could have also been the ringlands that were cracked on every single piston
Ill be sellin some stock rods that are in good shape, but nobody can buy my new paperweights
