The Infiniti G35 is a popular choice among car enthusiasts, known for its performance and style. One of the most effective ways to enhance its power and efficiency is by upgrading the intake and exhaust systems. In this article, we will explore the real-world results of installing an Injen Cold Air Intake and a Borla Exhaust system on the Infiniti G35, which can lead to impressive gains in horsepower.
Understanding the Upgrades
Before diving into the results, it’s essential to understand what these upgrades do. The Injen Cold Air Intake allows for a greater volume of cooler air to enter the engine, improving combustion efficiency. Meanwhile, the Borla Exhaust system reduces back pressure, allowing exhaust gases to exit more freely, which can enhance engine performance.
Installation Process
The installation of both the Injen Cold Air Intake and Borla Exhaust is relatively straightforward for those with basic mechanical skills. Here’s a brief overview of the steps involved:
- Gather necessary tools: socket set, wrenches, and screwdrivers.
- Lift the vehicle securely using jack stands.
- Remove the factory air intake system.
- Install the Injen Cold Air Intake according to the manufacturer’s instructions.
- Remove the factory exhaust system from the headers to the rear.
- Install the Borla Exhaust system, ensuring all connections are secure.
Performance Gains
After the installation, many drivers have reported significant performance improvements. On average, the combination of the Injen Cold Air Intake and Borla Exhaust can yield a gain of approximately 60 horsepower. This increase not only enhances acceleration but also improves overall driving experience.
Dyno Results
To quantify the performance gains, many enthusiasts have taken their vehicles to a dynamometer (dyno). Typical results show:
- Stock G35 horsepower: approximately 280 hp.
- Post-upgrade horsepower: approximately 340 hp.
- Torque increases: around 40 lb-ft.
Sound and Driving Experience
In addition to performance gains, the exhaust note changes significantly with the Borla system. Drivers often describe the sound as deeper and more aggressive, enhancing the sporty feel of the G35. The combination of improved airflow and sound can make driving more enjoyable.
Considerations and Recommendations
While the upgrades provide substantial benefits, there are a few considerations to keep in mind:
- Ensure proper installation to avoid any air leaks or exhaust leaks.
- Consider tuning the engine after upgrades for optimal performance.
- Check local regulations regarding emissions and noise levels.
Conclusion
The Infiniti G35 can achieve remarkable performance enhancements with the installation of an Injen Cold Air Intake and a Borla Exhaust system. With gains of up to 60 horsepower, improved sound, and an overall better driving experience, these upgrades are a worthwhile investment for any G35 owner looking to elevate their vehicle’s performance.
