Fine wire plugs provide 1-2 percent better fuel economy, so they pay for themselves well before they wear out in 2000-2500 hours. RAM Aircraft published findings on the topic. In which time you will have had to buy 3 or more sets of massive plugs, and pay for gapping and cleaning that fine wires don't need. Unless you go butterfingers and drop your spark plug tray, then cost-effectiveness goes out the window... 1 Quote Link to comment Share on other sites More sharing options...
