What are some recommended upgrades for the Nissan Navara's engine?

I recently purchased a Nissan Navara and I'm looking to improve its performance. Can anyone suggest any upgrades or modifications for the engine? I want to get the most out of my Navara.

One upgrade I highly recommend is a cold air intake system. It will increase airflow to the engine and improve its performance.

You could also upgrade the exhaust system to a high-flow one. This will improve exhaust flow and give your Navara a nice rumble.

A performance chip or programmer can also make a big difference in horsepower and torque. It's a relatively easy upgrade to install.
