AAP did not have the AC Delco plugs for a Trailblazer and these were the cross referenced plugs. They seem too be well made. They only have a few hundred miles on them, so we will see how they hold up. They did restore power and mileage that had been lost.

Not a direct replacement

This item is not a direct replacement as the website stipulates. Only copper plugs are a direct replacement for Hemi engines. Ask Chrysler.

        Comments about Autolite Double Platinum Spark Plugs:

        I'm just your everyday garage mechanic that doesn't mind getting my hands dirty to do my own routine maintenance. I am realistic by thinking that I wouldn't expect my vehicle to gain major horsepower or fuel economy by just changing spark plugs. I grade success by the fact they were easy to change out, and I didn't lose any power or fuel economy (may have gained, but I can't tell the difference as the GM I-5 is not exactly known for its acceleration/torque and plugs won't change that. I did however have to reset the gaps by closing down to the engine manufacturers setting. As received the gaps were all very large (>0.060").

                    Oem states 0.044" gap. These plugs come with a 0.060" gap. Does the gap need to be adjusted.
