Genuine CYFS12Y1X Spark Plug for Ford Focus 2013-2015 2.0

Genuine CYFS12Y1X Spark Plug for Ford Focus 2013–2015 2.0 is an important part of the ignition system, designed to create an electric spark to ignite the air-fuel mixture in the engine combustion chamber.

During operation, the spark plug works continuously in a high-temperature, high-pressure environment. If the spark plug is worn, carbon-fouled, or has reduced ignition performance, the engine may be hard to start, vibrate, use more fuel, and run less efficiently.

This product is a genuine Ford/Motorcraft spark plug, made with high-quality materials, strong heat resistance, and stable ignition durability, meeting the manufacturer's original assembly standards. It is suitable for the Ford Focus 2.0 model years 2013–2015, ensuring a precise OEM fit and full compatibility with the engine system.

In addition to ignition, the spark plug also helps optimize fuel combustion, supporting smoother acceleration, lower emissions, and better fuel economy in real-world driving.

Using genuine spark plugs helps maintain stable engine performance, reduce the risk of ignition system damage, and ensure long-lasting, reliable operation.
