- 1). Install a cold air intake system. A cold air intake system will provide your Sport Trac with more air at a lower temperature, causing the eventual fuel and air mixture that enters the cylinders to be more volatile. The increased volatility provides for bigger explosions and increased performance.
- 2). Replace the stock gears to a set with a more aggressive gear ratio. A more aggressive gear ratio will increase the performance of your Sport Trac by keeping your engine in the optimal power band for longer, though like most performance upgrades it will be at the cost of comfort and fuel efficiency.
- 3). Replace many of the stock parts with lightweight parts. The hood, drive shaft, and drive pulleys are popular choices for lightweight replacements. A lighter weight Sport Trac is easier to move, and will allow you to get more performance from your engine.
- 4). Install a supercharger. A supercharger is the single biggest performance upgrade you can install for your Sport Trac. A supercharger provides your engine with compressed air, allowing for an extremely potent fuel air mixture that will dramatically increase the performance of your Sport Trac.
