What are the best modifications for maximizing fuel efficiency in my Toyota Hilux?

I recently purchased a Toyota Hilux and I'm looking to make some modifications to improve its fuel efficiency. What are some recommendations for modifications that can help me achieve better gas mileage?

One of the most effective modifications you can make is to re-gear your Toyota Hilux. This will ensure that your engine is operating at its ideal RPM range, leading to improved fuel efficiency.

Upgrading to a more efficient exhaust system can also make a significant difference in fuel economy. Consider investing in a high-flow exhaust to improve your Toyota Hilux's performance.

Another modification to consider for better fuel efficiency is installing a cold air intake. This will allow your engine to breathe more easily and can result in improved gas mileage.
