Direct-Fit Oxygen Sensor

NTK 24249 is a direct-fit heated oxygen sensor built for specific applications and engineered for OE-style fit, form, and function. It uses a threaded mounting design with a 4-wire configuration and a 20.5-inch harness for a clean replacement path.

Key Features

  • Heated oxygen sensor for precise exhaust feedback
  • Specific-fit design for straightforward application matching
  • Threaded mounting type with 18 mm thread diameter
  • 20.5-inch wiring harness for proper routing
  • 4-wire sensor configuration

Detailed Description

NTK 24249 is part of the Direct Fit Oxygen Sensor line, a product line focused on application-specific replacement and broad coverage. NTK is known for oxygen sensor manufacturing and uses ceramic technology control from raw material through finished production. This sensor is manufactured and tested to meet or exceed OE specifications, making it a strong match for drivers replacing a worn sensor on a Honda S2000.

Fits 2004-2005 Honda S2000, upstream. This part cross-references DENSO Auto Parts (e.g., 234-4368) and BBB Industries (e.g., 13959) for the same application.

What It Helps Address

  • Faulty oxygen sensor readings
  • Check engine light concerns related to sensor performance
  • Improper air-fuel feedback from a worn sensor
  • Exhaust monitoring issues at the upstream location

Installation Notes and Quality

Install as a direct-fit replacement using the threaded mounting design and verify harness routing before final connection. Confirm the application by year, make, model, and upstream position before installation. NTK states these oxygen sensors are extensively tested during manufacturing to support quality and reliability that meet or exceed OE specifications.
