How to Achieve 300+ Hp in Your Infiniti G37: Best Intake and Exhaust Mods

The Infiniti G37 is a popular choice among car enthusiasts looking to enhance performance. With the right modifications, achieving over 300 horsepower is entirely possible. This article will guide you through the best intake and exhaust modifications to help you reach that goal.

Understanding the Infiniti G37 Engine

The G37 is powered by a 3.7-liter V6 engine, known for its smooth power delivery and strong performance. To maximize horsepower, it’s essential to understand how the engine works and the factors that affect its output.

Best Intake Modifications

Upgrading the intake system is one of the most effective ways to increase horsepower. A high-performance intake allows for better airflow, which can lead to significant gains in power.

Cold Air Intake Systems

A cold air intake (CAI) system is designed to draw cooler air from outside the engine bay, which is denser and contains more oxygen. This can result in improved combustion and increased horsepower.

  • Injen SP Series Cold Air Intake
  • Stillen Gen 3 Long Tube Intake
  • JWT Pop Charger Intake

Short Ram Intake Systems

Short ram intakes are another popular option. They are typically easier to install and can provide a noticeable increase in throttle response, although they may not offer the same gains as CAIs.

  • AEM Short Ram Intake
  • K&N 69 Series Typhoon Intake
  • Takeda Momentum Intake

Best Exhaust Modifications

After upgrading the intake, the next step is to enhance the exhaust system. A performance exhaust can significantly improve airflow out of the engine, which is crucial for maximizing horsepower.

Cat-Back Exhaust Systems

A cat-back exhaust system replaces the exhaust components from the catalytic converter back. These systems are designed to reduce back pressure and improve exhaust flow, leading to increased horsepower.

  • Invidia Gemini Cat-Back Exhaust
  • Fast Intentions Cat-Back Exhaust
  • Stillen Cat-Back Exhaust

High-Performance Headers

Upgrading to high-performance headers can also yield significant horsepower gains. Headers improve exhaust flow and can help the engine breathe more efficiently.

  • Motordyne Long Tube Headers
  • Stillen Headers
  • ISR Performance Headers

Tuning for Maximum Performance

After installing intake and exhaust modifications, tuning the engine is essential to maximize performance. A proper tune can optimize fuel delivery and ignition timing, ensuring that your G37 performs at its best.

  • ECU tuning with UpRev
  • Custom tuning from a reputable shop
  • Using a handheld tuner like the Cobb Accessport

Conclusion

Achieving 300+ horsepower in your Infiniti G37 is attainable with the right intake and exhaust modifications. By investing in quality parts and ensuring proper tuning, you can unlock the full potential of your engine and enjoy an exhilarating driving experience.
