What is the best strategy for maintaining the performance of a Kia Sportage's turbocharger?

I've noticed a decrease in the acceleration and power of my Kia Sportage, which I suspect is due to a poorly maintained turbocharger. What steps should I take to prevent this issue and keep my car's turbocharger functioning at its peak?

Regularly inspect and replace the air filter to prevent debris from clogging the turbocharger.

Always let the engine cool down for a few minutes before turning off the car to prevent oil from clogging the turbocharger.

Avoid aggressive driving and excessive engine revving as it can put strain on the turbocharger.

Consider investing in a high quality synthetic oil to prevent carbon build-up in the turbocharger.
