Just thought I would let everyone know just in case. Check the plug gap before installing new plugs. I bought 4 new AC Delco plugs for my 2014 1.4L that were supposed to be pre-gapped at 0.028 They were not! All of them were wrong ranging from 0.022 to 0.024

A simple $1.50 tool was all I needed to confirm it and fix it.

Furthermore when I removed the stock plugs from the factory (car has 39800 miles) the gap was wrong as well. The car is running much better with the plugs gaped correctly. I wonder if the assembly line just slammed them in there without caring
The workers on the line have seconds to do their job, repeating it for 8hrs straight. They do not have time to check gaps before installing them. Its ultimately the responsibility of the supplier to ensure the parts they supply, meet specifications
