Detailed Explanation
The Toyota Corolla is a popular compact car that has been in production since the late 1960s. Over the years, the Corolla has undergone numerous design and engineering changes, but one consistent component has been the spark plugs used in its engine.
Spark plugs play a crucial role in the internal combustion engine of a vehicle, providing the electrical spark that ignites the air-fuel mixture in each cylinder. The size of the spark plug is an important specification, as it needs to fit the cylinder head and thread size of the engine.
For the Toyota Corolla, the standard spark plug size is 14mm. This means the diameter of the threaded portion of the spark plug that screws into the cylinder head is 14 millimeters. This is a common size used in many Toyota, Lexus, and other Japanese vehicle models, as well as some domestic and European vehicles.

It's a good idea to consult the owner's manual or a trusted mechanic to determine the appropriate spark plug replacement schedule for your specific Corolla model.
