Cold Air Intake for Honda S2000 (2000-2005) 2.0L 2.2L Engines

Optimize F-Series Airflow: Cold Air Intake for Honda S2000 AP1 & AP2

Who It’s For: Engineered for Honda S2000 owners running the high-revving F20C or F22C1 powerplant who are tired of the stock airbox choking their top-end performance.

The Symptom: The factory intake on the F-Series engine was designed primarily to meet drive-by noise regulations, not to maximize the potential of the VTEC crossover. It utilizes a bulky, baffled resonator box and a corrugated “accordion” style inlet hose that creates massive air turbulence as RPMs climb. This results in a sluggish transition into the high-cam profile and a muffled engine note that hides the S2000’s true racing pedigree.

The Engineering Fix: This system replaces the restrictive plastic plumbing with a mandrel-bent T304 aluminum tube. By utilizing a constant-diameter pipe with a smooth internal surface, we significantly reduce the Reynolds number of the incoming air, ensuring laminar flow directly into the throttle body. By straightening the airflow path and increasing air density, this kit provides a sharper throttle snap and allows the engine to breathe freely all the way to its 8,000+ RPM redline.

Why Mechanics Choose This Kit

• Enhanced Torque Curve: By optimizing fluid dynamics, this kit helps fill in the mid-range dip, providing up to a 10% increase in horsepower and torque through the VTEC transition.
• Aggressive Induction Note: Removes the factory baffles to reveal a deep, metallic induction roar that transforms into a high-pitched scream at high RPM.
• Thermal Management: The lightweight T304 aluminum construction dissipates heat faster than stock plastics, while the high-flow cotton filter is washable and reusable for up to 50,000 miles between cleanings.
