What's the best way to increase horsepower in my Nissan Navara?

I've been looking for ways to boost the performance of my Nissan Navara and I'm wondering what are the most effective methods to increase horsepower. Any suggestions?

One of the easiest and most cost-effective ways to increase horsepower in your Nissan Navara is by installing a cold air intake system. This will allow your engine to breathe in more air, which can result in a noticeable power increase.

Upgrading your exhaust system can also have a significant impact on horsepower. A high-flow exhaust system will allow your engine to expel exhaust gases more efficiently, resulting in improved performance.

Another option is to tune your engine's ECU (Engine Control Unit). This involves reprogramming the computer that controls your engine's performance, allowing you to optimize horsepower and torque.
