so i read all the info on the thread about copper plugs. thought it would be a good idea to change mine since it had been some time. got the ngk brk6e's and gapped them to .28 and low and behold, what a difference! the iridium were totally shot, get pics later, and were gapped about .45
question is: do i need to visit my revo dealer for any adjustments?
ps - and yes i need a vagcom
