Review on 🚗 Enhance Your Vehicle's Performance with Motorcraft Spark Plug, SP-534/SP-580 by Jason Stokes

Bought six for my 2011 F150 Ecoboost after the stock spark plugs started burning the ceramic and misfiring bad enough to stop fix the code bugs. The original had 74,000 miles on the odometer. After replacing the spark plugs with new ones, all the problems went away. I drove about 5000 km with new spark plugs. Time will tell about the durability. Please note that at the time of writing this review the SP534 is the correct connector for your Ecoboost. The original OEM forks that were factory installed had a different part number, but Ford tweaked the fork design a bit.
