How can I improve my Audi A8 performance?

I recently purchased an Audi A8 and I feel like the engine could use some upgrades for better performance. Are there any specific modifications or maintenance tips you can recommend?

First of all, congratulations on your new Audi A8! To improve its performance, I suggest checking and possibly upgrading the air intake system. A cold air intake can greatly increase horsepower and torque. Additionally, consider installing a performance chip to optimize engine power and fuel economy. Regular maintenance such as oil changes and spark plug replacements can also greatly benefit performance.
