How often should the spark plugs of a BMW X3 be replaced?

BMW X3's spark plugs need to be replaced every 50,000 to 60,000 kilometers, and the spark plug model is SILZKGR8B8S. The BMW X3 is an SUV model with body dimensions of 4717mm in length, 1891mm in width, and 1689mm in height, with a wheelbase of 2810mm. In terms of power, the BMW X3 is equipped with a B48 2.0T turbocharged engine, which has a maximum power of 185kw, a maximum horsepower of 252ps, and a maximum torque of 350nm. In terms of the transmission system, the BMW X3 engine is paired with an 8-speed automatic manual transmission and also offers a four-wheel drive system.
Having driven the BMW X3 for so many years, I believe spark plug replacement depends on both the age of the vehicle and driving habits. My 2018 X3's manual recommends changing them every 80,000 kilometers or 4 years. Since I often encounter city traffic jams, spark plugs are prone to carbon buildup, and when they age, starting delays and a sharp increase in fuel consumption occur. Once, I delayed replacement until 60,000 km, and the car shook violently—repairs cost me 2,000 yuan, much more expensive than just replacing the spark plugs. So, I suggest checking the spark plug gap during regular maintenance; darkened color is a sign of aging. Getting them inspected at a 4S shop with professional tools is more accurate. This not only improves acceleration performance but also protects the engine and extends its lifespan, saving on major repair costs—definitely worth it. Based on my experience, replace them at 60k for city driving, or 80k if you drive less on highways.
Just became a BMW X3 newbie, consulted with a mechanic, spark plugs are recommended to be replaced every 5 years or 100,000 kilometers, depending on the model year. My car is a new model, the manual states to check at 60k kilometers. Common issues include aging causing slow acceleration, high fuel consumption, or difficulty starting. Usually observe the car's condition, for example, if cold starts are rough in winter, it might be a sign. Regular maintenance avoids major faults, at the dealership their system will automatically remind you. Ignoring spark plug replacement may lead to engine failure, costing more. So as a newbie, I keep a maintenance log, simple and reassuring.
I've always been passionate about car maintenance. The lifespan of BMW X3 spark plugs varies depending on the engine; high-performance versions are recommended at 30k miles, while standard versions at 50k miles. Iridium alloy materials are more durable. When aging, ignition weakens, increasing emissions. I've DIY replaced them myself - simple but requires professional tools. Neglecting it affects performance, especially during cold starts. Regular replacement improves fuel efficiency, saving money and being eco-friendly. Following the manual is the right way to go.
