LOL, and now a word from the resident geologist...hahaha
first of all...we were talking about NGK Iridium plugs, secondly changing plugs every 15k on a good running engine is a waste of money. and thirdly no one was debating the fact that adding fuel/air, etc yields more power...the discussion was about spark plugs and which ones are better...but I see that some people just want to steer the topic elsewhere so.....
