5. High-Performance Spark Plugs

Replacing your stock spark plugs with high-performance options ensures better combustion and ignition. This small change can have a big impact on your 4Runner’s overall performance.

6. Install a Turbocharger or Supercharger

For serious power gains, consider installing a turbocharger or supercharger. These forced induction systems can significantly increase horsepower, turning your 4Runner into a beast on the road.

7. Upgrade the Fuel System

A high-flow fuel system, including larger injectors and a high-pressure fuel pump, can provide the necessary fuel delivery for your power-boosting modifications.

8. Performance Exhaust Headers

Swap out your stock exhaust headers for high-performance ones. They improve exhaust flow, resulting in better engine response and increased power.

9. Quality Engine Oil

Using high-quality synthetic engine oil reduces friction and wear, ensuring your engine runs smoothly and efficiently.
