2021 Cadillac Escalade ESV V8 6.2L with Square Style Coil Ignition Kit TRQ TKA01333

Products came undamaged which is good. Couldn't work on the truck until about a week after receipt but as soon I as did install everything, and the engine was running rough. I knew there were misfires so had to throw the the code reader on and had issues in 3 of the cylinders... not thinking it could be the spark plugs I spent the better of an hour swapping wires and coil packs. Finally I looked at the spark plug cause noticed else made sense and noticed there was literally 0 gap on all the spark plugs. Thank God I have a gap tool but now I have to go back into the truck after buttoning up everything (because it was too late that night) and regap the rest of them. This was insane for me to see with my own eyes and the second time I have an issue with 1a auto... I'm probably gonna just start shopping somewhere else.

Usually you guys are spot on. NOT so much for 02 sensors. Bought (3), had have trouble twice that ended me up at the dealership for check engine light. Has cost me over $300 to have them correct the problem.
