Default Spark Plugs for 1.4LT engine

The OEM spark plugs installed in the 1.4LT engine are manufactured by NGK and packaged as ACDelco. To date, there have been three different ACDelco part numbers listed in the Cruze Owners Manuals:

2011 - ACDelco 41-117
2012 - ACDelco 41-120 (IFR6Z7G), 41-121
2013 - ACDelco 41-121

The 41-117 and 41-120 spark plugs are discontinued and only the 41-121 spark plug is now available. The NGK item number for the ACDelco 41-121 spark plug is NGK-91039 and its NGK descriptive SKU number is IFR7X7G, which translates (decodes) as:

I = Plug Type: Iridium Platinum
