ACDelco GM Original Equipment 41-122 (12681655) Iridium Spark Plug

Excellent product

I have replaced old Bosch plugs with this; 1000 km and car is stable and i have no problems with it; Smooth and nice, fuel consumption has dropped; Happy with the price;You get 1 instead of 4 as in the photo; another problem is that if the packaging is dent, you will need to recheck the gap; otherwise nice plugs;

$15 dollars cheaper then local dealership

Since I replace my old spark plugs with these. My 2014 Chevy Cruze been driving so much better. Check engine went off in my gas mileage has improved. Highly recommend

The pictures lead you to believe that it comes with 4 spark plugs but only comes with one. Definitely cheaper price than picking them up locally at a auto parts store as they run about $13.49 each at autozone. So buyer beware if your doing a tune up it sucks to open the package and see only one plug.

I got 4 of these to replace the 4 that were in my engine. My Volt had started misfiring and if you have ever had to commute more than 40 miles (each way) for work, then you will understand how traveling 38 miles on surface streets instead of the freeway can really put a damper on your time...these along with a replacement Coil pack (corrosion of the spring contacts inside the boots) and I was good to go again.Thanks for reading! Cheers!!

every single one was gapped wrong(very carefully) regap all of the plugs you buy

These work very well. I noticed an improvement right away upon doing a tuneup 30,000 miles better economy and good firing.
