    I have been running Autolite iridiums for 82,000 miles in my Hemi with great results. I'm going to be changing them soon.

    I would recommend just staying with the oem. Depending on which motor you have. I have the 4.7 liter and have had about 5 different sets of plugs and am now back to the oem champion plugs.

    I just bought a new set of Autolites Iridiums on eBay. 16 plugs for $90. BTW, there's a nice rebate running. Go to the Autolite website to see. I'll get $32 back on the 16 plugs I bought. Sweet!

    I have the Denso iridium plugs. Spent too much but they have been great plugs. It took 4+ hours to change the 16 plugs (for me - I am a mechanic wannabe) so I thought the iridium might last 50-60K instead of the recommended 30K miles
