How often should the Leiling spark plugs be replaced?

[DelLydia]

The Leiling spark plugs should be replaced every 40,000 to 50,000 kilometers. The Leiling spark plugs are platinum spark plugs. If the wear is significant, they should be replaced as soon as possible. The function of the spark plug is to introduce the high-voltage electricity (over 10,000 volts) generated by the ignition coil into the engine cylinder, creating a spark between the spark plug electrode gaps to ignite the air-fuel mixture. The Leiling is a compact sedan built on Toyota's MC platform. In terms of body dimensions, it measures 4640mm in length, 1780mm in width, and 1455mm in height, with a wheelbase of 2700mm. In terms of exterior design, the Leiling adopts the styling of the North American version of the model. The front face features more lines compared to the previous version, with raised front fenders on both sides. The headlights have been redesigned into a hook-like style, and the rear has undergone minor styling changes, featuring a black horizontal chrome strip that runs across the taillights. The lower black trim wraps around the rear, transforming the previously purely family-oriented image.
