How to improve the performance of the BMW i8?

I've been experiencing some lag in my BMW i8's performance lately. What could be causing this and how can I fix it?

One possible reason for the lag in performance could be a clogged air filter. It is important to regularly check and replace the air filter to ensure optimal performance.

Another potential issue could be dirty fuel injectors. It's recommended to get them cleaned every 30,000 miles or so to maintain the engine's efficiency.

I also suggest checking the spark plugs and replacing them if necessary. Worn out spark plugs can significantly affect the car's performance.
