How to replace Spark Plugs | 2016+ Honda Civic (10th Gen)

I replace the spark plugs on a 10th generation Honda Civic which are model years 2016, 2017, 2018, 2019, 2020, and 2021. This engine was a 2.0 L K20C2 It uses a 14mm spark plug that are set deeper in the engine. To access the spark plugs you remove the wire harness, the plastic cover, the ignition coils, and then you can remove the spark plugs. A very handy tool to have is a rubber spark plug installer. It prevents you from stripping the threads which will damage the cylinder head.
