[MaxAnn]

Toyota Corolla spark plugs should be replaced every 100,000 kilometers or approximately 5 years. To extend the lifespan of the spark plugs, it is recommended to regularly clean the air filter to prevent dust from entering the combustion chamber with the air-fuel mixture, which can corrode the spark plugs. Additionally, you can remove the spark plugs yourself to clean the ignition head of dirt and carbon deposits. The Toyota Corolla has a body length of 4635mm, width of 1780mm, height of 1455mm, and a wheelbase of 2700mm. It is equipped with a 1.2T turbocharged engine paired with a CVT transmission, delivering a maximum power of 85kW and a maximum torque of 185Nm.
