This is a set of four NGK (NGK Spark Plug) ignition coils, U5248, for one vehicle. These ignition coils offer superior performance thanks to the advanced ignition system technology and strict quality standards cultivated over NGK's long history of spark plug development. Internal combustion engines using spark plugs require a high voltage of 20,000 to 35,000 volts to generate a spark in the combustion chamber during the compression stroke. An ignition coil is a type of transformer that converts 12V into the high voltage required for spark plug discharge. This product is a pencil coil type, so it attaches directly to each spark plug, eliminating the need for plug cords.
