NGK iridium plugs...
i couldn't find if it's been posted...
but has anyone seen the actual hp gains they boast from using these plugs? i've heard that it is supposed to be 10-15 hp gains.
also if the gains are there, but you don't have a custom computer chip, will the difference be there without the computer being programmed for the difference in the plugs?
thx for any info!
