S2000 Ap2 Intake & Header Upgrades: How Much Power Do They Actually Add?

The Honda S2000 AP2 is a beloved sports car known for its high-revving engine and exceptional handling. Enthusiasts often seek ways to enhance its performance, particularly through intake and header upgrades. This article will explore how much power these modifications can actually add to the S2000 AP2.

Understanding the S2000 AP2 Engine

The S2000 AP2 features a 2.2-liter F20C engine that produces around 240 horsepower and 162 lb-ft of torque. This engine is known for its high redline and responsiveness. However, many owners look to boost these numbers through aftermarket modifications.

Intake Upgrades

Upgrading the intake system can significantly impact engine performance. A high-flow intake allows for better airflow, which can lead to improved throttle response and increased horsepower.

Types of Intake Upgrades

  • Cold Air Intakes
  • Short Ram Intakes
  • High-Performance Filters

Power Gains from Intake Upgrades

On average, a quality intake upgrade can add between 5 to 15 horsepower, depending on the specific model and installation. Additionally, these upgrades can improve engine sound and aesthetics under the hood.

Header Upgrades

Header upgrades replace the factory exhaust manifold with a more efficient design. This modification can reduce back pressure and improve exhaust flow, leading to performance gains.

Types of Header Upgrades

  • Long Tube Headers
  • Shorty Headers
  • Performance Exhaust Manifolds

Power Gains from Header Upgrades

Header upgrades can yield a power increase of approximately 10 to 20 horsepower. The exact gains depend on the specific headers chosen and the overall exhaust system configuration.

Combined Intake and Header Upgrades

When both intake and header upgrades are performed, the cumulative effect can be significant. Many enthusiasts report total gains of 15 to 35 horsepower when combining these modifications.

Factors Influencing Power Gains

  • Quality of the Parts
  • Installation Quality
  • Supporting Modifications (e.g., ECU tuning)
  • Vehicle Condition and Maintenance

Real-World Examples

Several S2000 AP2 owners have documented their experiences with intake and header upgrades. Here are some real-world examples:

  • Owner A: Installed a cold air intake and long tube headers, resulting in a total gain of 30 horsepower.
  • Owner B: Upgraded to a short ram intake and performance headers, achieving a 25 horsepower increase.
  • Owner C: Combined both upgrades with ECU tuning, reporting a 40 horsepower gain.

Conclusion

Intake and header upgrades for the Honda S2000 AP2 can provide noticeable power gains, enhancing the overall driving experience. While individual results may vary, enthusiasts can expect improvements in performance, sound, and responsiveness. Always consider the quality of parts and proper installation to maximize gains and ensure reliability.
