How often should the GL8 spark plugs be replaced?
1 Answers
GL8 spark plugs should be replaced every 2 years or 40,000 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 sparks by jumping across the electrode gap, thereby igniting the combustible air-fuel mixture in the cylinder. A spark plug mainly consists of a terminal nut, insulator, terminal stud, center electrode, side electrode, and shell, with the side electrode welded to the shell. The GL8 is an MPV under SAIC-GM Buick. Taking the Buick GL8 2021 Land Business Class 652T Comfort model as an example, it features a 5-door, 7-seat body structure, a 66-liter fuel tank, and a powertrain equipped with a 2.0L inline 4-cylinder turbocharged engine, delivering a maximum power of 174 kW and a maximum torque of 350 Nm, paired with a 9-speed automatic transmission.
