Spark Plugs

Spark plugs are a critical component of gasoline engines, responsible for igniting the air-fuel mixture within the combustion chamber. Located in the engine cylinder head, these parts deliver a high-voltage spark to initiate combustion, powering the vehicle. Spark plugs are characterized by their heat range, thread size, gap specification, and electrode material - all crucial for optimal engine performance and efficiency. Modern spark plugs often feature platinum, iridium, or copper electrodes for increased durability and consistent spark delivery. Examples in this category include Bosch spark plugs like MPN 0242236571, as well as those designed for Audi, BMW, and Volkswagen vehicles, and Bosch MPN 0241140537. Properly functioning spark plugs contribute to improved fuel economy, reduced emissions, and reliable engine operation for passenger cars and commercial vehicles.
