Honda S2000 Cold Air Intake Install: How a $300 Upgrade Can Add 10-15 Hp

The Honda S2000 is a beloved sports car known for its high-revving engine and thrilling performance. One of the most popular upgrades among S2000 enthusiasts is the installation of a cold air intake (CAI). This relatively simple modification can provide a noticeable boost in horsepower and improve engine responsiveness. In this article, we’ll explore the benefits of a cold air intake, how to install one, and the expected performance gains.

Benefits of a Cold Air Intake

A cold air intake system allows your engine to breathe better by drawing in cooler air from outside the engine bay. This cooler air is denser and contains more oxygen, which can lead to improved combustion and increased horsepower. Here are some key benefits of installing a cold air intake on your Honda S2000:

  • Increased Horsepower: A cold air intake can add 10-15 horsepower, depending on other modifications.
  • Better Throttle Response: Improved airflow leads to quicker engine response.
  • Enhanced Sound: A CAI can give your S2000 a more aggressive engine sound.
  • Improved Fuel Efficiency: Better airflow can lead to increased fuel efficiency under certain driving conditions.
