Review on 🚀 Enhanced Performance with Motorcraft SP537 Spark Plug: A Game-Changer for Your Vehicle! by Brian Edwards

These spark plugs are defective. I replaced them on my 2017 60k just to keep up with the maintenance of my car and after about 100 miles or about 4 days the car starts to misfire so I check everything and everything looks fine so I have the same ones Bought spark plugs but at the Ford dealer , and replaced again, now a few weeks have passed and the car runs very quietly. The good thing is I send them back to Revain and get my money back, the bad was a waste of time.
