3 Answers
The original spark plug model for the Focus 1.6L engine is LTR6GP, while the 1.0T and 1.5T engines use ILZNAR8A7G. The spark plug is a key component in the automotive engine's ignition system, responsible for introducing the high voltage generated by the ignition coil into the engine cylinder, creating a spark across the electrode gap to ignite the air-fuel mixture. The Focus is a vehicle produced by Changan Ford, with body dimensions of 4342mm in length, 4820mm in width, and 4480mm in height. The Focus features a new family design language, with a refreshed large grille that enhances its stylish and refined appearance. Additionally, the ST-Line version has been introduced, with a body height that is 10mm lower than the standard model.
I've been driving my Focus for several years and recently replaced the spark plugs myself. The original model is NGK IZTR6J11, which is quite common on 1.5L engines. However, if you have a different model year, such as pre-2017, it might come with ILKR8P7 instead. Why does this matter? OEM spark plugs are the most reliable match for your engine. Using the wrong brand can lead to issues like misfiring or increased fuel consumption. The replacement interval is typically every 30,000 to 50,000 kilometers. When I last changed mine, I noticed heavy carbon buildup and decided to replace them early to avoid breakdowns. Before you start, check the manual or consult a repair shop to confirm the model—don’t just cut corners. Regular spark plug checks can also extend your engine’s lifespan, saving you hassle in the long run.
As a long-time car enthusiast, I believe the original spark plug model for the Focus is typically determined by the engine type. Most Focus models, like the 2.0L Ecoboost, come with NGK IZTR6J11, but Bosch FR7HI332 is also common. The main difference in models lies in the heat range, and the original match ensures ignition stability to avoid premature wear. When replacing spark plugs, don't skimp on quality—using the wrong model can cause engine misfires or starting difficulties, seriously affecting driving safety. For regular maintenance, check the plugs and gaps every six months. If the car is older, consider upgrading to high-performance spark plugs. Note: Always disconnect the power before replacing them to ensure safety. The removal and installation process is straightforward, but don't handle it carelessly.
