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.
As a regular at the repair shop, we recommend replacing the spark plugs for the BMW X4 every five years or 80,000 kilometers, with specific reference to your owner's manual. Different engines, such as gasoline and hybrid versions, may have variations; four-cylinder engines typically require replacement at 60,000 kilometers, while six-cylinder engines can last up to 100,000 kilometers. Worn spark plugs can cause weak ignition, unstable idling, or warning lights. I recommend checking the spark plug gap wear during maintenance at a BMW 4S shop to avoid roadside breakdowns. We've handled several cases where delayed replacement led to failure to start, so timely maintenance saves both hassle and money.
As a young car owner who just got a BMW X4 two years ago, the spark plug replacement interval is approximately every five years or 70,000 kilometers. BMW's maintenance guide suggests considering driving intensity; frequent highway driving can extend the interval. Don't stress too much—as long as the car starts quickly and accelerates smoothly, it's fine. But if you notice engine shaking or a sudden spike in fuel consumption, head to the shop for a replacement. The cost isn't high, just a few hundred bucks, and regular maintenance keeps the car running smoothly.
