Comparing Power Gains: Aem and Skunk2 Intake Manifolds on S2000 Ap2

by

The Honda S2000 AP2 is a beloved sports car known for its high-revving engine and exceptional handling. One of the most common modifications enthusiasts consider to enhance performance is the installation of an aftermarket intake manifold. This article compares two popular options: the AEM and Skunk2 intake manifolds, focusing on their power gains and overall performance impact.

Understanding Intake Manifolds

Intake manifolds play a critical role in an engine’s performance by directing air into the combustion chamber. The design and flow characteristics of an intake manifold can significantly affect an engine’s power output. In the case of the S2000 AP2, upgrading the intake manifold can lead to noticeable improvements in horsepower and torque.

AEM Intake Manifold Overview

The AEM intake manifold is designed to increase airflow and improve engine performance. It features a larger plenum and optimized runner design, which helps to enhance throttle response and power delivery. Here are some key features of the AEM intake manifold:

  • Increased plenum volume for better airflow.
  • Optimized runner lengths for improved torque.
  • Lightweight construction for reduced overall weight.
  • Compatible with stock throttle bodies and aftermarket options.

Skunk2 Intake Manifold Overview

The Skunk2 intake manifold is another popular choice among S2000 enthusiasts. Known for its aggressive design, the Skunk2 manifold aims to maximize airflow and engine efficiency. Below are some notable features of the Skunk2 intake manifold:

  • Large plenum volume for enhanced power gains.
  • Advanced runner design for optimal air distribution.
  • Durable construction materials for longevity.
  • Designed for high RPM performance.

Power Gains Comparison

When comparing the power gains from both the AEM and Skunk2 intake manifolds, it’s essential to consider various factors such as engine tuning, supporting modifications, and driving conditions. Below is a summary of the expected power gains from each manifold:

  • AEM Intake Manifold: Typically provides a power increase of 15-20 horsepower at peak RPM.
  • Skunk2 Intake Manifold: Generally offers a power increase of 20-25 horsepower at peak RPM.

Torque and Throttle Response

In addition to peak horsepower, torque and throttle response are critical aspects of engine performance. Both intake manifolds are designed to improve these characteristics, but their effects can differ:

  • AEM Intake Manifold: Known for enhancing low to mid-range torque, making it suitable for daily driving.
  • Skunk2 Intake Manifold: Tends to excel in high RPM torque, ideal for track-focused builds.

Installation and Compatibility

Installation of an intake manifold can be a straightforward process, but it requires attention to detail. Here’s what to consider for each manifold:

  • AEM Intake Manifold: Direct bolt-on fitment, compatible with stock components, making installation easier for beginners.
  • Skunk2 Intake Manifold: Also a bolt-on design but may require additional tuning for optimal performance.

Cost Considerations

Cost is always a factor when considering aftermarket parts. Here’s a rough estimate of the pricing for both intake manifolds:

  • AEM Intake Manifold: Priced around $500-$600.
  • Skunk2 Intake Manifold: Typically ranges from $600-$700.

Real-World Performance Testing

Several enthusiasts have conducted real-world performance tests to evaluate the power gains of both intake manifolds. Here are some findings:

  • Dyno tests show that both manifolds provide significant power increases, but the Skunk2 often edges out in peak numbers.
  • Drivers report that the AEM manifold offers a more linear power delivery, which is beneficial for street use.

Conclusion

Choosing between the AEM and Skunk2 intake manifolds for the Honda S2000 AP2 ultimately depends on the driver’s goals and preferences. The AEM intake manifold is excellent for those seeking a balance of power and drivability, while the Skunk2 manifold is better suited for those focused on maximizing performance at higher RPMs. Both options offer substantial gains and can significantly enhance the driving experience.

Further Modifications to Consider

When upgrading your intake manifold, it’s wise to consider additional modifications that can complement the performance gains. Here are some recommendations:

  • High-performance exhaust systems for improved airflow.
  • ECU tuning to maximize the benefits of the new manifold.
  • Upgraded fuel injectors to ensure proper fuel delivery.
  • Cold air intakes for better air quality and temperature control.
