What brand of spark plug is fomoco?

fomoco is a spark plug produced by Ford Focus. What types of spark plugs are there: Main types of spark plugs include: standard spark plugs, extended tip spark plugs, electrode spark plugs, seat spark plugs, pole spark plugs, and surface gap spark plugs. Replacement cycle for spark plugs: Under normal maintenance conditions, replacement is recommended after driving 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine. It is advisable to follow the user manual. You can refer to the following standards for maintenance replacement: platinum spark plugs should be replaced at 40,000 kilometers, ordinary nickel alloy spark plugs at 20,000 kilometers, and iridium spark plugs at 60,000 to 80,000 kilometers. Working principle of spark plugs: Under high voltage, the air between the center electrode and the side electrode of the spark plug will rapidly ionize, forming positively charged ions and negatively charged free electrons. When the voltage between the electrodes reaches a certain value, the number of ions and electrons in the gas increases like an avalanche, causing the air to lose its insulating properties and forming a discharge channel, resulting in a 'breakdown' phenomenon. At this point, the gas forms a luminous body, known as a 'spark.' Along with the thermal expansion, a 'snapping' sound is also produced. The temperature of this electric spark can reach as high as 2,000-3,000°C, which is sufficient to ignite the air-fuel mixture in the combustion chamber of the cylinder.
As a Ford owner who has been driving Ford vehicles for over a decade, FoMoCo spark plugs are essentially genuine Ford parts, with the Motorcraft brand being their in-house production. Spark plugs are critical components in the engine for ignition, and when they age, they can easily cause unstable idling or increased fuel consumption. I often change them myself—a set of genuine ones costs about 150 yuan, slightly more expensive than aftermarket brands but more durable. Generally, they should be inspected every 50,000 kilometers, and if the electrode gap is too large, they need to be replaced. During regular maintenance, pay attention to the engine sound; if there's any abnormality, address it early to avoid a breakdown on the road and unnecessary delays.
