Stick to oem
Gave me P0420. I thought the catalytic converter was clogged. It was actually one of the spark plugs that was broken. Replaced them and it was fixed. Happy customer here.

Excellent Plug but their shipping SUCKS
The plug was exactly what I Ordered. However, I ordered 5 and they shipped each one individually. I received 3, one was damaged and returned to sender, and another just simply never made it to me. They did refund my money but what a pain in the rear!!

These AC Delco 41-103 Iridium are the correct replacement part for the 41-981 discontinued platinum
2004 GMC Envoy XUV . I tried to go cheaper but i ended up having to get these as the correct replacemet part. This is somewhat complicated due to the original plug 41-981 Platinum plug was discontinued and replaced with these 41-103 plug was hard to get to so i think whatever mechanic did the first tune up left the original in there. So theres alot of plugs that wont fit right that will say they are correct wont fire or are not the correct quality and the first plugs i ordered did not even fire. So In Short In This Case I Would not try to go cheap and Go With These AC Delco plugs they fired immeditely and correctly.

I bought these spark plugs for my 2006 Chevrolet Trailblazer on Jun 2022 and I kept them as spare for my car. Today I decided to replaced my spark plugs and one of these new spark plugs broken while tightening! The quality of these new spark plugs is not as supposed to be and now I have to spend hundreds to fix my car.

I've learned over fifty years of car ownership and self-maintenance that the best spark plugs to buy are the exact ones that the car was built with. Nothing else. Ignore the fancy claims as "platinum" or "Iridium" etc as they are still a compromise plug. Extra cost of the fancy ones notwithstanding.
