FJ12SP Posted August 22, 2009 Share Posted August 22, 2009 Hi Skindog I have used/am using Iridium plugs dont notice any performance increase, but they last a long time. Just changed them after 12,000 miles and they looked almost new. Adam. Link to comment Share on other sites More sharing options...
cootertwo Posted September 12, 2009 Share Posted September 12, 2009 I love them. Put a set in my Harley, and noticed a difference as soon as I hit the starter. Great plugs for sure! Link to comment Share on other sites More sharing options...
