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

Terrible packaging. Was hanging out of a crushed package box and then just placed in an envelope. Product was made in Thailand which is probably a a knockoff. Google search indicated this.

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!!

These are great spark plugs. Worked perfectly on my Chevy cruze.

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

top quality, reasonable price.

Excellent produit d'origine, fabrication NGK!
