Just replaced the plugs after about 60,500mi and used suggested factory plugs. Changing them out is easy for 1, 3 and 4....just a 10mm bolt for the coil and a 5/8" deep socket with a 6" extension to unseat and then used a telescopic magnet tool to remove. Getting the second cylinder ignition coil (front to back of engine is 1-4?) is a little tight with the diverter valve especially if you have a DV+ installed. Had to remove some of the sensor connectors without breaking the tabs and wiggle it out.
One this that was concerning was after removing each plug there was black soot flakes that came out from the cylinder. See how dark the threads are. The past 15,000mi have been fairly short distance trips (<5mi) of less than 20min back and forth. Camera makes the plug look a little darker than it actually is, slightly more brownish than dark.
If anyone is interested in what 2.0 2018 plugs look like at about 60,000mi which is the change interval per Jeep.
Upgrades:
