iridium spark plugs

[AnDy7]

Does anyone use iridium spark plugs? and if so what do u think about them?

I have one in my Son's CRF120F and haven't had any problems. It sopposedly has a stronger, hotter spark to allow for a more complete burn on ignition. The only real down fall is they are very wicked expensive. I might try one on my 416EX once I get it jetted properly.

Iridiums buy you more plug life then performance. I doubt any gain would be found on a dyno. They do typically hold up better in harsh conditions.

there mainly used for bikes that are harder to start, like a cr500.. they require less energy to spark.
