Smooth out a rough or hunting idle with the Standard Ignition Idle Air Control Valve AC573. It drops in as a direct-fit OE replacement for the 2001 Nissan Altima [L4-2.4L], metering the amount of air that bypasses the throttle plate so the engine can hold a steady idle speed across cold starts, warm-up, and accessory loads. If a failing idle air control valve is the cause of your unstable idle, stalling, or surging, this replaces it.

  • Direct-fit OE replacement: designed to install like the original for ease of installation on the listed application.
  • Electrical connection: 2 female connectors with blade-style male terminals (2 + 2), plus a single hose connector.
  • Built to endure: high-quality materials made to withstand extreme conditions.
  • Quality controlled: undergoes extensive testing for reliability, backed by complete quality control throughout manufacturing.

Made in Japan.
