Does anyone know where one can get the best price on Iridium Aviation spark plugs for the Lycoming 0-320?

Looks like the going rate is about 65 bucks ea. I put them in right after initial startup on my new 0-360 A1A. The OEM massive electrode plugs fouled during initial testing, so I switched to the iridium plugs. I had great experience using them in my Cherokee, so I decided to use them in my 7A. I think they are worth the expense and are certainly more trouble free than the massive electrode style.

I love um, we have them in the bottom of the Cardinal right now. Massives in the top. That will save a few bucks. Also look into the autolite versions, slightly cheaper I believe and Autolites seem to work good in the field IMHO.

Save your money, and use Auto lites instead of Champs.
