These were great. Most importantly they were real.
Buying Iridium Spark Plugs online is often a horror show with some estimates being that 60% of them are counterfeit. I have learned this the hard way having to re-replace a set of fakes that required the intake manifold to be pulled in order to change the plugs. I was very pleased when I received these, performed all the checks and tests on them and found them to be genuine AC Delco plugs. I even examined the Iridium tip under a microscope. High quality at a very reasonable price, 5 Stars.

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.

Great sparkplugs
Changed the sparkplugs (same AC Delco Iridium plugs) on my 2005 GMC Canyon which had almost 100,000 miles on them. The truck ran fine but with the new plugs I have more zip and it's running smoother. Haven't put enough miles on to check the mpg difference yet.

Always check the gap!
I bought 6 of these and the mfg says to NOT set the gap on iridium plugs. They're set at the factory. BS. After installing them and trusting they were gapped correctly at the factory, I had a random misfire. Turns out one plug gap was so bad it was almost closed. Otherwise, the car runs great and gets better mpg over the old plugs.

Great price Great plugs
These are the OE replacements for a 02 Chevy Trailblazer Ext. Performed a tune up and these plugs are great. They’re already gapped however I always check the gap! My wife’s SUV runs great!

OEM Replacement for the Win
Great quality from original equipment manufacturer. I always look for AC Delco parts 1st to guarantee that I’m getting the best part for my Chevrolets. Easy to install and improved the rough start issue I was having. If I have to replace one, I go ahead and replace them all at once for the best results.
