spark plug
I am needing new spark plugs for a 2006 Chevrolet HHR and I was wondering what the difference was between the AC DELCO 41-103 and 41-105. I don't see anyone selling the 41-103 like someone suggested I get.

I found the 41-103 plugs at Autozone and Advanced autoparts online like here
shop.advanceautoparts.com/p/acdelco...iridium...41-103/15650269-
it shows this fits the 2.4 liter engine for the 2006 model
the 41-105 shows for the 2.2 liter engine for the 2006 model

Good job Oldblue!
The 2006 2.2L Ecotec engine was a Generation I version of the power plant, hence the requirement for Iridium 41-105 plugs.
2007 and newer Ecotec engines use the revised Generation II block and cylinder head, hence a different plug number.
There are enough differences between the '06 and '07 Ecotec 2.2 engines, both minor and major, that the 2006 engines are really considered "stand alone" models.
