I just replaced my spark plugs on my 2012 1.4T with the ACDelco 41-121 ones.
I have a Champion 20 Ton model with the 196cc engine. I have used it for 5 years, splitting about 35-40 cords. The only issue I have had is I had to replace the spark plug once. The engine still works well but just in case I bought a direct replacement Power Fist Chonda engine for $229 CDN.
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.
Champion is garbage.
Champion aren't a great brand. They may have been at one point, but not any more.
BEWARE O’REILLY’S AUTO PARTS CHAMPION SPARK PLUGS ARE WEAK AND BREAK AT THREADS AFTER HAND TIGHTENING AND THEN TIGHTENING NOT EVEN A QUARTER INCH OF A TURN, WAY BEFORE THE TORQUE SPEC AND THEY TWIST RIGHT OFF N BREAK.
Like everyone has mentioned just go back with an ac delco plug. I ran champions and had Mis fires, none of them were gapped right out of the box.
