The Mazda NA Miata is a beloved sports car known for its lightweight design and engaging driving experience. For enthusiasts looking to enhance their vehicle’s performance, a common upgrade path involves the intake and exhaust systems. This article explores the real-world results of investing $1,000 in an intake and exhaust upgrade for the NA Miata, focusing on the gains in horsepower and sound quality.
Understanding the NA Miata
The first-generation Mazda Miata, produced from 1989 to 1997, is often praised for its simplicity and driving dynamics. With a lightweight chassis and a peppy 1.6-liter engine, the NA Miata provides a solid foundation for performance upgrades. However, as with any vehicle, enhancing airflow through the intake and exhaust systems can lead to noticeable improvements.
The Upgrade Process
For this upgrade, we focused on two key components: the intake system and the exhaust system. Together, these modifications aim to improve airflow, resulting in increased horsepower and a more aggressive sound profile.
Intake Upgrade
The intake upgrade involved replacing the factory airbox with a high-performance cold air intake system. This type of system is designed to draw cooler air from outside the engine bay, improving combustion efficiency. The installation is relatively straightforward and typically requires minimal mechanical expertise.
Exhaust Upgrade
The exhaust upgrade consisted of a cat-back exhaust system designed to reduce back pressure and enhance exhaust flow. A quality cat-back system not only improves performance but also alters the sound of the vehicle, giving it a sportier, more aggressive tone.
Performance Results
After completing the intake and exhaust upgrades, we conducted a series of tests to measure the performance gains. The results were impressive, showing a significant increase in horsepower and noticeable improvements in sound quality.
- Horsepower Gain: The upgrades resulted in an increase of approximately 15 horsepower at the wheels.
- Sound Quality: The new exhaust system provided a deeper, more resonant tone, enhancing the driving experience.
Driving Experience
The upgrades transformed the driving experience of the NA Miata. With the additional horsepower, acceleration felt more responsive, and the car was easier to push through corners. The improved sound from the exhaust system added to the excitement of driving, making each trip more enjoyable.
Cost vs. Benefit Analysis
Investing $1,000 in these upgrades may seem steep, but the benefits in terms of performance and driving enjoyment are substantial. Here’s a breakdown of the cost versus the benefits:
- Cost: $1,000 for intake and exhaust upgrades.
- Benefits: 15 additional horsepower, enhanced sound, improved acceleration, and overall driving pleasure.
Conclusion
Upgrading the intake and exhaust systems of the NA Miata is a worthwhile investment for those looking to enhance their vehicle’s performance. With a gain of 15 horsepower and a more engaging sound profile, these modifications significantly improve the driving experience. For enthusiasts, the $1,000 spent on these upgrades can lead to a more thrilling and enjoyable ride.
