I was browsing, and I noticed that Bosch is now listing a double iridium spark plug for the Cruze. I cannot find it available anywhere, but they have a part number for it. It looks like the Bosch double iridium plugs were introduced late last year.
Bosch 96306

These are copper core spark plugs with a fine wire iridium center electrode and an iridium inlay on the ground electrode. The PDF brochure on the site says the ground electrode also has a copper core and they reduce voltage requirements by up to 24%.
Iridium has lower electrical resistance than Platinum and Nickel, which means these could potentially be better than both the OEM plugs and the nickel plugs everyone has been using.
Anyone heard of these?
