Spark plugs.
My car just rolled past 200,000 miles so I wanted to replace the spark plugs before they failed. They came pre-gapped (which I checked) and they are a great value for the money. These also have the fit, quality, and performance I'm looking for.

Good plugs, description inaccurate
Amazon said that the factory gap is .050 in. It is actually .040 in. Otherwise the plugs work well, and I am getting 4mpg more than I was on the factory plugs. 2012 fusion.
