How can I improve the performance of my Kia Sportage's engine?

I noticed that my Kia Sportage's engine is not performing as well as it used to. What can I do to improve its performance? Should I use any specific type of fuel or additives?

First, make sure to follow the recommended maintenance schedule for your Kia Sportage's engine. Regular oil changes and tune-ups can greatly improve performance. You can also try using a higher octane fuel or adding a fuel injector cleaner to your fuel tank.

Another option is to upgrade your air intake system or install a performance chip. These modifications can increase horsepower and overall engine performance.

If you've noticed a decrease in performance over time, it could be due to a clogged air filter or dirty fuel injectors. Try replacing these components to see if it makes a difference.
