How often should the spark plugs of a BMW X4 be replaced?

The spark plugs of a BMW X4 should be replaced every 50,000 kilometers. At 50,000 kilometers, it's time for a major maintenance service. In addition to the regular replacement of engine oil and the three filters, the throttle, brake fluid, and coolant should also be cleaned. The spark plugs should be replaced again at 100,000 kilometers. The BMW X4 is a mid-size SUV introduced by BMW, featuring a unique xDrive all-wheel-drive system that enhances its performance in terms of power. The BMW X4 adopts a front-engine, four-wheel-drive layout with an on-demand all-wheel-drive system. The front suspension of this vehicle uses a double-joint spring strut front axle suspension, while the rear suspension employs a five-link rear suspension. The chassis has been specially tuned to reduce body roll during acceleration and cornering.
I've been driving a BMW X4 for seven years and have replaced the spark plugs twice. The experience is that they should be changed every 60,000 to 100,000 kilometers or so. The BMW official manual recommends checking based on your car model and driving habits; if you frequently encounter city traffic jams, you should replace them earlier. I usually check them at around 70,000 kilometers. Not replacing them in time can cause engine shaking, startup issues, a surge in fuel consumption, and even affect the engine's lifespan. Once, I drove until 90,000 kilometers before replacing them, and the car's acceleration was particularly sluggish—it became smooth immediately after the repair. I suggest having a technician check the spark plug condition during regular maintenance. Don't try to save on maintenance costs to avoid spending more on car repairs later.
