Iridium is just a type of metal. Since it's harder than the copper (or whatever) that makes up the electrode of a standard spark plug, it can be refined into a finer point with no degradation in longevity. In theory this will give you a better spark. Some people swear by them. We have found them to hold up better in our racing applications over a standard plug in the real world, so they aren't all just hype.

Iridium
Justification! It's so they can justify charging you 10X what a sparkplug is really worth!! Buy the $2 spark plug and lose 10#, you'll see the same increase in power on a china scoot.

Hey Irish, have you checked the Harley Forums, for what others with your engine use?
This is what I did, (but I went to BMW Forum) and found several recommendations for an Autolite 3923 plug, for my particular bike. This was a little more than 2 years ago, a two pack was $3.21 at Wallyworld. Still work fine, but I have only put 6,500 miles on them, so no big surprize. My scooter is still running the standard NGK that came in it. I have suffered no power loss, or decrease in fuel mileage, yet.....8,300 miles. Some swear by iridium, or the Split Fire (that was a big thing a while back), I've just never seen the need. Probably a generational thing.....you know....the old dog, and new tricks, kinda deal. |
