dodgethis Posted May 30, 2009 Report Share Posted May 30, 2009 Hey I just thought Id start another thread about the thread talked about replacing wires and plug. I thought about changing from boschs platnium plus to ngk iridium plugs. I didnt know that you cannot use a regular spark plug gapper on iridium because of the possiblity of breaking off the coated electrode. I found this information at http://www.srtforums.com/forums/f77/how-properly-open-gap-ngk-iridium-plugs-469472 Is this true guys? Quote Link to comment Share on other sites More sharing options...
RareGMFan Posted May 30, 2009 Report Share Posted May 30, 2009 Yes, that's standard info when it comes to iridium plugs. I wouldn't bother wasting the money on them. They're not worth the price in the least bit. Quote Link to comment Share on other sites More sharing options...
