94937 LZKR6B-E Set Of 4 Pieces Of Premium Spark Plug With High Performance And Long Lasting Material

OverviewA set of 4 car spark plugs includes four individual spark plugs, one for each cylinder in the engine. The spark plugs in a set are designed to work together to provide consistent ignition performance and ensure the smooth operation of the engine. When purchasing a set of spark plugs, it is important to choose the correct type and heat range specified by the vehicle manufacturer to maintain optimal combustion and prevent potential engine issues. Regularly replacing the entire set of spark plugs is recommended to maintain balanced engine performance and prevent variations in ignition quality among cylinders. The replacement interval for a set of spark plugs varies depending on the spark plug type and the manufacturer's recommendations, typically ranging from 30,000 to 100,000 miles. When installing a new set of spark plugs, it is important to follow the manufacturer's instructions and torque specifications to ensure proper seating and prevent damage to the spark plug threads or the engine cylinder head. Inspecting the condition of the spark plugs in a set regularly, such as checking for fouling, wear, or damage, can help identify potential engine problems and ensure optimal ignition system performance. Upgrading to performance spark plugs within the same heat range may provide improved ignition efficiency and potentially enhance engine performance, especially in high-performance or modified vehicles. It is recommended to keep a spare set of spark plugs in your vehicle as part of an emergency kit, especially during long trips or when traveling to remote areas where replacement parts may not be readily available.
