🔥 ACDelco GM Original Equipment 41-993 Iridium Spark Plug: High-Performance Ignition Component Review

do not be fooled by false advertising of this product they advertise a price of eight and you pay and then only send four until the other four come up totally bad advertising.

I bought them and found a $3 discount per connector on another site. Makes shopping even better. The candles are of excellent quality and have been installed without any problems on a boat with a Volvo Penta 5.0GXI-H engine. The engine runs great now. I definitely recommend it.

OEM replacement part for Vortec 5.7 engines. Plus others I'm sure. But specifically I have a 1997 Silverado, 5.7 engine. Please do not plug in these plugs. They are factory installed and must not be tampered with. The very small iridium electrode is fragile and should be left alone. If the boxes are damaged and the slots look closed, send them back for a replacement. Otherwise, just apply a non-stick coating and install as is. OEM connectors are always the best choice.

Started by ordering '8 pack' and only received 4. I figured no big deal, I'll order a second pack of 4 as I need 6. I received a second pack of 4 only to find that I received the wrong spark plugs. I will be returning one of the 4 packs and will purchase the last two spark plugs I need from O'Reilly. I won't waste any more time ordering them from Revain. Check the model numbers upon receipt! The second model I got is not even compatible with my truck.

THEY APPLIED A STICKER WITH CORRECT SPARK PLUG INFO SUCH AS ACDELCO 41-993 PT # 109063248 PAPER BOX because they know what I wanted and ordered for my 97 Chevy Surburban 8 Clinder 5.7L engine. Being a mechanic I always check the physical item before fitting and find that the spark plugs sent do not fit my Chevy. The spark plugs received are for marine engines and they say AC DELCO MR43T PT # 19355200. I want 8 correct spark plugs AC DELCO 41-993 PRE GAP .060 sent to my address free of charge…

product name "ACDelco 41-993 Professional Iridium Spark Plug (Pack of 8)"; but what you get is actually "ACDelco 41-993 Professional Iridium Spark Plug (Pack of 4)". Yes, these are the correct ACDelco 41-993 Iridium spark plugs; but you only get 4. At my request, Revain sent a replacement order and it was only for 4. But at least now I have the 8 I need. I made a correction to the product listing. Hope they fix it soon. Please note that at the time of writing this article there were various…

What's Going On Revain!? Your description clearly says there are 8 per pack! Not so fast, I only received a 4 pack! I understand that 8 outlets is very profitable, but I didn't say that, you did! I had to order the product again to have 8 spark plugs for my Silverado, I feel Revain has me covered! The item is fine and the delivery service was great! I contacted Revain customer service and the rep told me that the second order would indeed include spark plugs and I could return the first 4…

Arrived on time after ordering is perhaps the only plus in buying these forks. They are poor quality, they have a lifetime guarantee, all eight plugs have failed in three years! All of the iridium tips on these connectors are burning out and there is no answer for replacing these faulty connectors. I am very surprised and disappointed that Revain allowed them to remove my spark plug photo review. Luckily I still have the candles, I will take pictures and post them again as I had to give my…
