How Can I Increase the Performance of My BMW 7 Series?

I have a BMW 7 Series and I feel like it doesn't have the same power as it used to. What could be causing this and how can I improve its performance?

One possible reason for decreased performance could be a clogged air filter. Try replacing it with a new one for improved air flow and increased horsepower.

Another thing to check is the spark plugs. Over time, they can wear out and cause engine misfires. Replacing them with high-quality, performance spark plugs can make a noticeable difference in your car's acceleration.

Make sure to also regularly check and change your car's oil. Old, dirty oil can decrease engine performance and even cause damage. Stick to the manufacturer's recommended oil change intervals for best results.
