OEM Spark Plugs

Spark plugs are vital for your engine's performance in vehicles like the Ford Mustang and Ford Focus. They generate the spark needed to ignite the air-fuel mixture inside the engine, allowing your car to run. Over time, spark plugs can wear down and lead to performance issues. Knowing how spark plugs work, why they fail, and when to replace them can save you from costly repairs and help keep your engine running smoothly.

What Spark Plugs Do

Spark plugs are small components that ignite the air-fuel mixture inside the engine's cylinders, providing the spark necessary for combustion. Without them, your engine wouldn't run. They help ensure smooth engine operation, better fuel efficiency, and optimal engine performance. Keeping them in good condition is essential for maintaining the reliability of your vehicle.

Why Spark Plugs Break Down

Spark plugs naturally wear out over time due to the high heat and pressure inside the engine. As they age, carbon deposits can build up on the electrodes, leading to misfires and reduced performance. Other causes of failure include corrosion, cracking, or electrode erosion. When spark plugs fail, it can result in rough idling, sluggish acceleration, or poor fuel economy.

Why Genuine Ford Parts Are Best

For the best results, always replace spark plugs with genuine Ford parts. While aftermarket spark plugs may seem cheaper, they often don't meet the high standards of Ford parts, which are specifically designed for your vehicle. Genuine Ford spark plugs ensure better performance, increased reliability, and a longer lifespan. For other critical components, like your transmission, always opt for the genuine part to keep your vehicle running smoothly.
