Spark plug Autolite or AC DELCO

I just put in regular AC Delco plugs and it runs great.

Fresh AC Delco copper core plugs are all you need. Start with the stock replacements and go from there.

I just replaced my spark plugs on my 2012 1.4T with the ACDelco 41-121 ones.

Them Autolites are sweet, if they were edible I'd ask for them in my Kung Pow?

Use only AC DELCO ignition components for GM vehicles, and that includes spark plugs. The factory plugs work perfectly.

I replaced the spark plug with an Auto Lite spark plug. Engine light went away but still runs rough and misfire on acceleration.

If you need new spark plugs... Don't use Autolite.

Autolite plugs are junk. You’re better off leaving those 200k OEM plugs in it.

Throw those autolite plugs in the garbage where they belong

Yea,get some ngk’s or denso,autolite plugs are garbage.
