The AEM Cold Air Intake system has become a popular modification among NB Miata enthusiasts looking to enhance their vehicle’s performance. In this article, we will explore the dyno results that demonstrate how this intake system can boost power by up to 12 horsepower.
Understanding the AEM Cold Air Intake
The AEM Cold Air Intake is designed to increase airflow to the engine, which can lead to improved combustion and, ultimately, more power. By relocating the air filter outside of the engine bay, this system allows cooler air to enter the intake manifold. Cooler air is denser, meaning it contains more oxygen, which is crucial for combustion.
Key Features of the AEM Cold Air Intake
- High-quality aluminum construction
- Easy installation with no cutting required
- Reusable air filter for long-term savings
- Significant weight reduction compared to factory intake
Dyno Testing Methodology
To accurately measure the performance gains provided by the AEM Cold Air Intake, a controlled dyno test was conducted. The testing involved the following steps:
- Baseline runs with the stock intake system
- Installation of the AEM Cold Air Intake
- Multiple runs to ensure consistent data
- Comparison of horsepower and torque outputs
Results of the Dyno Test
The results of the dyno testing revealed a notable increase in power. The following data summarizes the findings:
- Stock Power Output: 104 HP
- AEM Cold Air Intake Power Output: 116 HP
- Power Gain: 12 HP
- Torque Increase: 10 lb-ft
Performance Benefits Beyond Horsepower
While the horsepower increase is a significant benefit, the AEM Cold Air Intake offers additional performance advantages:
- Improved throttle response
- Enhanced engine sound
- Better fuel efficiency under certain driving conditions
- Increased engine longevity due to lower intake temperatures
Installation Process
Installing the AEM Cold Air Intake on an NB Miata is straightforward and can typically be completed in under two hours. Here’s a brief overview of the installation steps:
- Gather necessary tools: socket set, screwdrivers, and pliers
- Remove the factory air intake system
- Install the AEM intake pipe and secure it with provided hardware
- Attach the reusable air filter and ensure a snug fit
- Double-check all connections and start the engine
Conclusion
The AEM Cold Air Intake is an excellent upgrade for NB Miata owners seeking to enhance their vehicle’s performance. With a proven increase of 12 horsepower on the dyno, along with other performance benefits, it represents a worthwhile investment. Whether you’re a casual driver or a dedicated enthusiast, this intake system can help you unlock the full potential of your Miata.
