Honda S2000 Airbox Resonator Blanking Plug

• Deep Induction Sound: Bypasses the factory noise-cancelling resonator chamber to amplify your intake volume under heavy throttle, mimicking the aggressive sound of an open aftermarket intake kit.
• 100% Reversible Design: Unlike other permanent solutions that require cutting out internal partitions, this plug allows you to return your car to factory-stock configuration in seconds.
• No Modifications Required: Features a strict zero-cut, zero-drill engineering design. Simply open your airbox lid, insert the plug over the internal resonator port, and secure it.
• Optimal Thermal Performance: Keeps hot under-hood air out of your engine. By keeping the factory airbox fully sealed and intact, you avoid the notorious engine heat soak common with open cone filters.
• Perfect OEM-Plus Fitment: Designed with precision tight tolerances to seat flush inside the factory airbox, maintaining a smooth internal air profile without obstructing filter placement.

• Vehicle Compatibility: Honda S2000 (AP1 & AP2 Models - 1999–2009)
• Material: ASA + Foam rubber seal
• Installation Time: Under 5 Minutes
• Tools Required: Alenkey 4mm
• Reversibility: 100% Removable

1. Open the Airbox: Unclip the 6 factory metal latches holding down the upper S2000 airbox lid and lift it out of the way.
2. Insert the Plug: Locate the square/round internal side port leading to the isolated resonator chamber and press the blanking plug firmly into place.
3. Seal and Drive: Reinstall your air filter, snap the airbox cover securely back on, and head out to enjoy your enhanced VTEC crossover sound!
