Cold Air Intake Kit for 2000-2005 Honda S2000 Base Convertible 2.0L & 2.2L DOHC

Honda engineered the S2000's F20C and F22C to within an inch of their lives — 120 hp per liter naturally aspirated, a 9,000 RPM redline, and one of the most responsive throttle calibrations ever put in a road car. But the factory intake prioritizes NVH suppression over induction theater. The sealed airbox, paper panel filter, and complex resonator plumbing silence the very VTEC scream that makes this car legendary. The engine breathes well — it just doesn't sound like it.

This Flashark intake replaces the restrictive factory airbox with a large-diameter, mandrel-bent aluminum intake tube and a high-flow dry-cone filter. The open-element design eliminates the intake silencing, letting the F20C/F22C's VTEC crossover at 6,000 RPM hit with the full-voice induction howl the car was built for. Power gains are modest — expect 3-5 wheel horsepower on a stock engine, because Honda already pulled 240 hp from 2.0 liters, and there isn't much left on the table. The real upgrade is the sharper throttle response above 4,000 RPM and the sound.

Installation is straightforward but requires patience. The S2000's stock airbox is buried behind the fender liner and takes some careful disassembly to remove. Once out, the Flashark kit mounts to factory bolt locations with the included bracket — no cutting, no drilling, no permanent modifications. Basic hand tools, 60-90 minutes, and your AP1 or AP2 finally sounds the part.

Key Features

Large-Diameter Mandrel-Bent Aluminum Intake Tube — Single-piece construction with integrated mounting points. Finished in heat-resistant matte black powder coat. Eliminates the restriction and silencing of the factory airbox and resonator assembly while delivering a smooth, uninterrupted airflow path.

High-Flow Dry Cone Filter — Red cotton-gauze media, washable and reusable. Dry-type filtration requires no oiling — critical on the S2000's MAP-based engine management, where filter oil is not a MAF contamination concern but adds unnecessary maintenance. Clean with filter cleaner, rinse, air dry, and reinstall.

Engineered for MAP Sensor Compatibility — The S2000 uses a speed-density (MAP/IAT) system rather than a mass airflow sensor. This means the ECU measures intake manifold pressure and temperature rather than airflow directly — it adapts to changes in intake without retuning or sensor recalibration. No MAF to worry about, no check engine light risk from airflow reading errors.

Direct-Fit Silicone Coupler — Bridges the intake tube to the throttle body with a precise, airtight seal. Heat-resistant silicone maintains flexibility and seal integrity through extreme underhood temperature cycles.

Complete Hardware Kit — All mounting brackets, clamps, breather connectors, and fasteners included. Everything shown is in the box — no extra parts to track down.

True Bolt-On Installation — Mounts to factory bolt locations. The stock airbox and resonator can be reinstalled at any time. No cutting, drilling, or permanent modification required. Note: removing the stock S2000 airbox takes some care due to its deep fender-well mounting — budget 60-90 minutes total.

VTEC Induction Scream — The open-element filter and aluminum tube unleash the F20C/F22C's VTEC crossover sound above 6,000 RPM. At wide-open throttle, the intake howl is sharp, mechanical, and addictive — exactly what these engines were engineered to produce before Honda silenced them for the showroom floor. At idle and light cruise, the sound is subtle and won't fatigue on long drives.

3-5 WHP on Stock Tune — Honest, realistic gain on a stock F20C or F22C. Honda extracted 120 hp/liter from these engines from the factory — there is no cheap horsepower left to unlock with an intake alone. The improvements you'll actually feel are crisper throttle response from 4,000 RPM up and a dramatically enhanced induction soundtrack.
