Professional 41-993 (19256067) Iridium Spark Plug (Pack of 1)

41-993 is the upgrade part number that is recommended for the 2000 Chevrolet S10 V6 vortec engine I've been using just any AC Delco spark plugs just cuz they would work. Although I wasn't getting the power, the performance the best quality out of my vehicle. For that reason I firmly suggest to use the part number that your vehicle recommends for that specific part. Do not cross number it just cuz it will serve the purpose and it's cheaper. Your vehicle just won't perform and our best manner as you would expect for it too. And it would be your you to blame. I myself didn't realize that as when I decided to do that. There was a great positive difference and I'm glad I did and I recommend everyone to do the same. You would be oh so glad when you do

Just installed these spark plugs today. AC Delco makes great replacement parts for my 1997 Chevy Silverado K1500 that always fit, last, and perform. These particular spark plugs are “pre gapped at 0.60” so they are correct and ready for installation right out of the box. My truck runs perfect again and the price for a pack of 4 plugs is VERY affordable.

Genuine OEM spark plug. The 8 that I installed had the gap already set to 0.060 which is what the vortec 5.7 gap is. Might be the same for other motors. The price beats local parts stores at 12 dollars a plug. I would still double check the gap on them but they did not need adjusted.

I bought 8 AC Delco Iridium spark plugs # 41-993. Gaped at 0.060" and packaged with a protective sleeve. Best of all they were manufactured in the U.S.A. and the price was lower than the imported brands.

These plugs are the best i have ever used get better gas mileage and engine runs so much better thanks again keep up the good work everyone

Seem good

What is going on here Amazon!? Your description CLEARLY states Pack of 8! Not so fast, I only received a pack of 4! I realize the great deal for 8 plugs but I didn't make that statement, You did! I had to reorder the product again to have 8 spark plugs for my Silverado, I feel like I got had by Amazon! The product is fine and the delivery service was great! Reached Amazon customer service and the representative told me that indeed the second order would contain spark plugs and I could return the first 4! LOL! NOPE, RECEIVED 4!Somebody, needs to correct the online info stating a pack of 8 to 4. Very misleading and misrepresenting the product which leads to aggravation!

The Product Name is "ACDelco 41-993 Professional Iridium Spark Plug (Pack of 8) "; but what you get is really "ACDelco 41-993 Professional Iridium Spark Plug (Pack of 4)". Yes, it is the correct ACDelco 41-993 Iridium spark plugs; but you only get 4. On my request, Amazon shipped a replacement order and it also only consisted of 4. But at least I now have the 8 that I need. I submitted a correction to the product listing. Hopefully it will get corrected soon. Note that as of this writing, there are various indications in the product listing small print that this is a 4 Pack. It is the main Product Name that is in error.
