Good plugs and great price. Just check the gap on them

Original factory plugs.

I ordered 7 spark plugs which are very fragile like eggs. When I opened the package, there was no stuffing in there to protect the spark plugs from damage. I was really surprised when I inspected and gapped the spark plugs that none of them were cracked. I installed them all and they all worked great. I gave you a 5 star because they all worked and I just got lucky this time.

These sparks plugs are a great value at only 20% or less of local auto parts stores prices.I purchased 8 plugs and half of them (4) had been mishandled so that the ground electrode was bent and touching the center electrode. The boxes did not show any unusual damage and they were packaged such that this type of damage probably would not occur. However it happened it must have been very rough handling to cause the electrode to come in contact with center. I accidentally dropped an undamaged one while checking the gap. It fell a little more than one foot onto a solid metal shelf directly onto the electrode and the gap remained unchanged. This indicates very bad mishandling somewhere between manufacturer and being placed into boxes.

Worked out great

Bought these back in May 2024 and have had no issues with them. As I said in the title AC Delco need I say more? It is what was in the old truck when I bought it and seen no reason not to put back what had it running good for all the years prior.
