Nice...was going to start searching for an iridium plug for my bike.

So, is there really an advantage to using a spark plug that will outlast the engine it's installed in?

it has to do with management of the combustion cycles - they are perfect for the life of the plug

I couldn't find that model. I did find a IW16 that Denso recommended for the FL EVO's. http://www.globaldenso.com/cgi-bin/g...&action=search

Is it the same?

sorry it was a typo 1W16 is the correct number in a shop cheap is not what we look for, as 3 / 4 years down the road the cost crosses and unless an issue should come up - push the button and go
