worth it
I was hesitant to pay extra cost for Iridium plugs but they are worth the extra money. Noticeable improvement in performance on 04 V-star 1100.

Best Spark Plugs!
Started to use these plugs in my last bike since every 3,000 miles i'd be re-gapping standard plugs. these(Iridium plugs) after 15,000 miles didn't even need any gap adjustment! bought a set for the new bike so i wouldn't need to worry about needing spark plugs again for a long time!
