Improving airflow into and out of the engine is crucial. An upgraded intake system can enhance air delivery, while a performance exhaust can reduce back pressure.
- Consider a cold air intake for better airflow
- Look for cat-back exhaust systems for improved sound and performance
4. Fuel System Upgrades
To support increased horsepower, the fuel system may need upgrades. This includes larger fuel injectors and a high-flow fuel pump.
- Upgrading to 550cc or larger injectors is recommended
- A high-flow fuel pump ensures adequate fuel delivery
