Spark plugs (SP143877AB) are a vital part of any vehicle ignition system. These components generate the necessary spark to ignite that air-fuel mixture in your carburetor to start your engine. The ignition will move the pistons in the engine and start the combustion process for producing power.

Since these auto parts constantly produce sparks for ignition, they are more prone to wear and tear due to the extreme pressure and temperatures inside the cylinders. Faulty spark plugs can cause frequent engine misfires and rough idling since the plugs can’t produce a consistent spark to ignite the air-fuel mixture. Other symptoms of failing engine spark plugs include reduced fuel economy, poor acceleration, and engine surging. If you’re having trouble starting your car consistently, your spark plugs might need to be replaced.
