Mazda Miata Performance Test: Comparing Gains from Different Cold Air Intakes and Ecu Tunes

The Mazda Miata is a beloved sports car known for its lightweight design and exceptional handling. Enthusiasts often look for ways to enhance its performance, and one popular method is through the installation of cold air intakes and ECU tunes. This article explores the performance gains achieved by different cold air intakes and ECU tunes for the Mazda Miata.

Understanding Cold Air Intakes

Cold air intakes are designed to improve the airflow to the engine, which can lead to better combustion and increased power output. By drawing cooler air from outside the engine bay, these intakes can enhance performance. Here are some key benefits:

  • Improved horsepower and torque
  • Enhanced throttle response
  • Better fuel efficiency

ECU Tunes Explained

An ECU (Engine Control Unit) tune modifies the software that controls the engine’s performance. By adjusting parameters such as fuel delivery, ignition timing, and boost pressure, a tune can significantly enhance the Miata’s performance. The advantages of ECU tuning include:

  • Increased horsepower and torque
  • Optimized fuel efficiency
  • Customizable performance settings

Testing Methodology

To accurately compare the performance gains from different cold air intakes and ECU tunes, we conducted a series of tests on a 2019 Mazda Miata. The methodology included:

  • Baseline dyno runs without modifications
  • Installation of each cold air intake
  • ECU tuning for each intake
  • Final dyno runs to measure performance gains

Cold Air Intake Options

We tested three popular cold air intakes for the Mazda Miata:

  • K&N 69-2020TS Typhoon Air Intake System
  • Injen SP Series Cold Air Intake
  • AEM 21-740C Cold Air Intake System

Performance Results

After completing the installation and tuning process, we measured the performance gains from each combination of cold air intake and ECU tune. Here are the results:

K&N 69-2020TS Typhoon Air Intake

The K&N intake showed significant improvements in horsepower and torque:

  • Baseline: 155 hp, 148 lb-ft
  • After Installation: 162 hp, 155 lb-ft
  • Gain: +7 hp, +7 lb-ft

Injen SP Series Cold Air Intake

The Injen intake provided even better results:

  • Baseline: 155 hp, 148 lb-ft
  • After Installation: 165 hp, 160 lb-ft
  • Gain: +10 hp, +12 lb-ft

AEM 21-740C Cold Air Intake

The AEM intake also yielded impressive gains:

  • Baseline: 155 hp, 148 lb-ft
  • After Installation: 163 hp, 157 lb-ft
  • Gain: +8 hp, +9 lb-ft

ECU Tune Comparisons

Next, we evaluated different ECU tunes to see how they complemented the cold air intakes:

  • Stock ECU Tune
  • Performance ECU Tune from Company A
  • Performance ECU Tune from Company B

Results of ECU Tunes

We measured the performance after applying each ECU tune with the Injen SP Series Cold Air Intake:

Stock ECU Tune

With the stock ECU tune, the performance was:

  • 165 hp, 160 lb-ft

Performance ECU Tune from Company A

The first performance ECU tune showed notable gains:

  • 175 hp, 170 lb-ft

Performance ECU Tune from Company B

The second performance ECU tune provided the best results:

  • 180 hp, 175 lb-ft

Final Thoughts

Through our testing, it is clear that both cold air intakes and ECU tunes can significantly enhance the performance of the Mazda Miata. The Injen SP Series Cold Air Intake, combined with the Performance ECU Tune from Company B, yielded the highest gains in horsepower and torque. Enthusiasts looking to maximize their Miata’s performance should consider these modifications for an exhilarating driving experience.
