I ordered the above spark plugs for my 2005 Chevy 5.3, but have since discovered there has been some confusion as to whether this plug will work in my 5.3. The manual calls for a plug # 41-985 but I understand GM changed to the 41-110 iridium plugs quite a few years ago. There is still some confusion all these years later. The 41-985 plugs are NLA from what I can gather. Is anyone else familiar with this conundrum and can enlighten me on whether the 41-110 plugs will work well in my 5.3? Thanks
