🔥 A Improved SEO-Friendly Version: ACDelco 41-962 Professional Platinum Spark Plug Set of 8 Review

They are worth the money and they are really good. They haven't been in use long enough for me to say they have any durability or mileage.

This is a complete fake. These spark plugs have only done 5,000 miles and are already bad. I went to the dealer and bought new spark plugs and you look at it. not compare at all. So outside of the return window I spent my money and had to do the work twice.

Great spark plugs for my 2001 Chevy Silverado 1500, made a huge difference in performance! Had a few random misfires before and this fixed the problem in addition to replacing all the wires with AC delco.

So far they work well for me and have eliminated my hesitation. Note. GM changed the recommended clearance from the original .0060 to .0040 inches. I reset it to 0.0040 and the truck rolled off the assembly line faster but quite hard and noisy and the gas mileage went down from 16mpg to 12. I reset it to 0.0060 and it's running smooth again. Fuel consumption has returned to normal.

The spark plugs in my 2002 Silverado required a .060 spark plug gap to be factory adjusted. I decided to change them at 70,000 miles and the spark plugs were preset at .060. With a circulation of 140,000, it's time to replace them again. ACDELCO candles (41-962) have been preset to 0.040. I should see if GM has done a rework before proceeding. As always, I'll buy my next set of plugs from an auto parts store. Less stress.
