    Compatible AC Delco Iridium Spark Plug Replacement P/N

    I cannot seem to find an AC Delco Iridium part number to replace the original platinum plugs (41-974) in our '03 Yukon, 5.3 L engine. We are at the 100k mile service and would like to upgrade to the iridium plugs. Thanks for any help/advice.
