How can I improve the performance of my Nissan Navara's engine?

I have noticed a decrease in power and acceleration in my Nissan Navara. What can I do to improve its engine performance?

First, make sure to regularly change the engine oil and air filter. This can greatly improve your engine's performance.

You can also try using a fuel injector cleaner to remove any deposits and improve fuel efficiency.

Check for any leaks in the intake system and replace any worn out spark plugs.
