Genuine Ford Focus Spark Plug 2015-2019 1.5 DS7G12405BA

Genuine Ford Focus 2015-2019 1.5 Spark Plug DS7G12405BA is an important part of the EcoBoost 1.5L gasoline engine ignition system, responsible for creating the spark in the combustion chamber to ignite the air-fuel mixture, helping the engine start easily, run smoothly and achieve optimal performance.

On Ford Focus models equipped with the 1.5L EcoBoost engine, the spark plug directly affects acceleration, fuel consumption, engine smoothness and emissions. A precise ignition spark helps the combustion process run completely, improving operating efficiency and reducing fuel waste.

The spark plug works by receiving high voltage from the ignition coil and creating an electric spark between the two electrodes in the combustion chamber. This process happens continuously thousands of times per minute while the engine is running, so the spark plug must withstand very high temperatures and pressure.

Over time, spark plug electrodes can wear down, become carbon-fouled or lose ignition performance, leading to engine vibration, hard starting, increased fuel consumption, reduced power or a check engine warning on the instrument cluster.

The genuine Ford product with part number DS7G12405BA is manufactured to the original manufacturer standard, ensuring stable ignition performance, long service life and full compatibility with the Ford Focus 1.5 EcoBoost engine system.
