Can a spark plug be removed from a NGK engine?
Thread breakage can sometimes involve removing the cylinder head for repair. Metal shell stretch changes the heat rating of the spark plug and can result in serious engine damage caused by pre-ignition. Do not use anti-seize or lubricant on NGK spark plugs. It is completely unnecessary and can be detrimental. 2. Corona stain
How do you read a NGK spark plug code?
How do you read a NGK Spark Plug code? The letter combination (1-4) before the heat rating indicates the thread diameter, hexagon spanner width and the design. The 5th position ( number) stands for the heat rating. The 6th letter identifies the thread length. The 7th letter contains data about special spark plug construction features.
What happens if the spark plug gap is wrong?

What to do if spark plug doesn’t lock up?
