    • Great buy.
I installed these in a 2011 Chevy pickup and they worked very good.

    • 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. ... show more

    • Nothing Better
In my opinion there is nothing better than an actual AC Delco product. In my vehicle nothing helps her run better. Prices are much better here than at the parts store. I will always recommend AC Delco parts above all others

    • Great OEM Plugs
First off, these plugs DO FIT a 2009 Chevy Trailblazer LT 4.2L 6L engine. I have no idea why Amazon thinks they don't. These are size 41-103 plugs and they are standard OEM equipment for my vehicle. They made my engine start and run so much better, immediately. They came packged great and were in perfect condition. I would certainly recommend these IF they fit your vehicle.
