The first generation Acura NSX is a celebrated model in the automotive world, known for its balance of performance and luxury. One common modification among enthusiasts is the installation of a cold air intake system. This article explores how much power the Injen cold air intake can add to the first gen NSX.
Understanding Cold Air Intakes
A cold air intake system is designed to increase engine performance by improving airflow. By drawing cooler air from outside the engine bay, these systems can enhance combustion efficiency, leading to more power. The Injen cold air intake is a popular choice among NSX owners for its quality and performance gains.
Benefits of the Injen Cold Air Intake
Installing an Injen cold air intake on your first gen NSX can provide several benefits:
- Increased Horsepower: One of the primary reasons for upgrading to a cold air intake is the potential increase in horsepower. The Injen system is designed to optimize airflow, which can lead to significant gains.
- Improved Throttle Response: A cold air intake can enhance throttle response, making the car feel more agile and responsive, especially during acceleration.
- Better Engine Sound: Many enthusiasts appreciate the deeper, more aggressive sound that a cold air intake can provide, adding to the overall driving experience.
- Enhanced Fuel Efficiency: With improved airflow, some drivers report better fuel efficiency, although this can vary based on driving habits.
Power Gains from Injen Intake
The exact power gain from the Injen cold air intake can vary based on several factors, including the condition of the vehicle, other modifications, and tuning. However, many NSX owners report an increase in horsepower ranging from 10 to 15 hp after installation.
Factors Influencing Power Gains
Several factors can influence the actual power gains experienced after installing a cold air intake:
- Engine Condition: A well-maintained engine will likely see better performance gains compared to one that is not in optimal condition.
- Additional Modifications: The presence of other modifications, such as exhaust systems or engine tuning, can compound the effects of the cold air intake.
- Tuning: Proper tuning after installation can maximize the potential gains from the cold air intake.
Installation Process
Installing the Injen cold air intake on a first gen NSX can be a straightforward process for those familiar with automotive work. Here’s a brief overview of the steps involved:
- Gather necessary tools and the Injen cold air intake kit.
- Disconnect the battery to ensure safety during installation.
- Remove the factory air intake system, including the airbox and associated tubing.
- Install the Injen intake system, ensuring all connections are secure.
- Reconnect the battery and start the engine to check for proper installation.
Conclusion
The Injen cold air intake is a valuable upgrade for first gen NSX owners looking to enhance performance. With potential power gains of 10 to 15 hp, improved throttle response, and an aggressive engine sound, it’s a modification worth considering. As with any performance upgrade, proper installation and tuning are essential to maximize the benefits.
