[DeAbigail]

Toyota Corolla spark plugs should be replaced every 80,000 to 100,000 kilometers. Spark plugs are a crucial component of the gasoline engine's ignition system, responsible for introducing high-voltage electricity into the combustion chamber and generating a spark by jumping the electrode gap to ignite the combustible air-fuel mixture in the cylinder. The Toyota Corolla is a compact car with body dimensions of 4635mm in length, 1780mm in width, and 1455mm in height, a wheelbase of 2700mm, and a fuel tank capacity of 50 liters. It is equipped with a 1.2T turbocharged engine, delivering a maximum power of 85kW, with the maximum power output achieved at 5200 to 5600 rpm.
