Great Plugs At This Price
Whatever the price, they provide good engine performance, completely the same as more expensive spark plugs do. I do not see any reason to buy other plugs for my Camaro.

Plugs
Refreshing replacement of OE plugs for my Outlander Sport. Feel no difference comparing them to the Bosh's plugs. Quality of the plugs is good enough.

Excellent Iridium Spark Plugs
Installed on my 2012 Chevy Avalanche despite filament table not being updated for this year. Pre-gap was perfect on all 8 plugs and installed easily. GMRebates.com has a rebate til the end of Sept, but need their part number on the invoice. Contacted customer support by email, and they promptly sent me the required document. Their price on these plugs was much better than other sites. Very good shipping and response times despite covid challenges.

ACDelco Professional Irdium Spark Plugs
My Tahoe had a miss while idling. I need plugs and wires since I had 150,000 miles on this vehicle. I found the recommended plugs at CARiD for $2 less per plug than any local store. I checked and found that I could get a $3 rebate on each plug as well. Package had 4 boxed plugs in each set of two. When time came to install the spark plugs, I was amazed that each of the 8 plugs were already set to the .040 gap recommended for my vehicle. I didn't have to adjust any of them. One of the old plugs that I removed from my Tahoe had a hair line crack in the area that would be stressed from adjusting the gap. I feel confident these plugs will give me long life without any problems. I did change the wires too.

Bought Inspiration For My Truck Performance
It made my 2009 Canyon run like a tiger champ. Iridium is known to be what the best plugs are made of. If you like having the best plugs per specification, this is your plug. I selected a reputable seller who offered good price.
