How can I improve the performance of my BMW X6 engine?

I have noticed a decrease in power and responsiveness in my BMW X6 engine. What steps can I take to improve its performance?

First, make sure you are using high-quality fuel and regularly changing your oil and filters. These basic maintenance tasks can greatly affect your engine's performance.

You can also try upgrading your spark plugs and ignition coils. This can provide a stronger, more consistent spark, resulting in improved engine performance.

If those measures don't work, you may want to consider a performance tuning or chip upgrade. This can optimize your engine's settings for maximum power and efficiency.
