Spark plug AC DELCO or BERU

I use only NGK or Beru spark plugs.

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.

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

AC Delco CR43TS.

Copper plugs are actually the best for performance, precious metals just last far longer.

I'd use the original equipment AC Delco plug. Rockauto has them for $6.31 each, with a $3 per plug rebate offered.

Standard replacement CR43TS Delco plugs, and a decent brand of wires. Bosch makes nice wires. Our engines don't exactly tax the ignition system, so if it's functional, you don't stand to gain much.

Had these Beru plugs put in last year. Are they the kind that’s at greater risk for damaging the engine?

I had the same experience and ended up getting a code. Swapped them out back to AC Delco and never had an issue.

These look like knockoff acdelco plugs.
