The iridium plugs that have replaced the platinum plugs, do not require gaping. They come pre-gaped. These long life plugs are coated and any gaping process may disrupt the coating causing premature plug failure. Replace the plugs at 80 -100,000 miles with AC Delco Iridiums. Check the plugs and ensure the protective sleeve is in place that protects the factory gap. www.trailvoy.com
