FAQ for Spark Plug Repair
Q: How to install the Spark Plug?
A:
You should measure the spark plug gap on the spark plugs to be installed, compare the measurement to the gap specifications, install the spark plugs to the engine, and be sure that the spark plug threads smoothly into the cylinder head and the spark plug is fully seated, clean threads in the cylinder head and cross-threading or failing to fully seat the spark plug can cause overheating of the plug, exhaust blow-by, or thread damage. Then, you should install the ignition coils.
