OEM Champion Spark Plug gapping is incorrect

While I was changing out the OEM battery, I took the liberty to check the gapping on the spark plugs. A bad habit with prior Dodges and Champion goof ups with proper gapping.

This is what I found:

CYLINDER #1: .046
CYLINDER #2: .047
CYLINDER #3: .046
CYLINDER #4: .044

Yes, like always, Champion never got it right when delivering the SRT-4 plugs to DCX.

However, the proper gapping is .050.

May have to try one colder range spark plug and see what happens. Along, with a 20 degree colder thermostat.

CHAMPION PLUG PART NUMBER: RE14MCCS

Cars that have 2.4 ltr motors that used the same spark plugs:

Stratus 2.4ltr
Galant 2.4ltr
Lancer 2.4ltr

However they use a RC12XXXX series vice the RE14 series plug.

I had check around and no cross reference of the RE14 series spark plug to an Iridium style plug. For that matter, no cross reference for the RE14 series plug at all.

I want to test these plug out on the car for further gains or just hype.

I now asked BJ for inside help from DCX.

What is this, a special Champion spark plug that only DC carries and does not crossreference to other brands?
