I would like to replace the spark plugs in my 2017 Cruze LT HB with a colder heat range iridium plug. Rock Auto shows the following but I can't seem to find any info on the differences. I would appreciate any help.

41-151, 41-153, 41-156

You have the 1.4T, right? Why are you seeking a colder plug? smile

How many miles are on your Cruze? Any modifications?

Yes. Why would you want/need to go to a different plug?

The 2017 an possibly 2016 Cruze uses a different plug than previously it is a very long reach the OE plugs have a 14mm hex and a taper seat instead of a gasket. The BKR8EIX plugs I bought are very different.

I wanted a colder plug with a slightly smaller gap as I am planning on running the BNR tune with a lead foot :-)
