NGK 24586 NTK O2 Sensor Front Upstream for 1997-1999 Acura NSX 3.2L V6

Vehicle Fitment

• 1997-1999 Acura NSX (3.2L V6, RWD)
• 1997-1999 Acura NSX-T (3.2L V6, RWD)

Fitment Notes

• Position: Front Upstream oxygen sensor.
• Designed for the 3.2L V6 C32B engine used in 1997-1999 NSX applications.
• 1991-1996 NSX 3.0L V6 applications use different oxygen-sensor part numbers and are excluded.
• 2000-2005 NSX 3.2L V6 applications use different cataloged oxygen-sensor configurations and are excluded.
• Verify the required bank and sensor position before ordering because the NSX uses multiple oxygen sensors.
• Direct-fit connector eliminates the need for cutting or splicing the factory wiring.

Features

• NTK by NGK OE-type switching oxygen sensor.
• Direct-fit replacement for the specified Acura NSX application.
• Heated four-wire oxygen-sensor design.

Product Description

The NGK 24586, manufactured by NTK, is a direct-fit heated switching oxygen sensor designed for the front upstream position on 1997-1999 Acura NSX models equipped with the 3.2L V6 engine. The sensor provides the engine control system with exhaust oxygen information used to monitor and regulate the air-fuel mixture, helping maintain proper fuel-control operation.

This four-wire sensor uses a 24.75-inch lead and an application-specific connector for installation into the factory wiring harness. Its 18 mm M18 x 1.5 threaded body is designed for the specified factory exhaust location, while the heated construction allows the sensing element to reach operating temperature efficiently. NTK's ceramic sensing technology and platinum interface are engineered for OE-style response, durability, and resistance to exhaust contaminants.

The 24586 is specific to the front upstream oxygen-sensor position on the 1997-1999 3.2L NSX application. Because the NSX uses multiple oxygen sensors and sensor specifications vary between model years and engine configurations, verify the exact year, engine, bank, and sensor position before installation. The sensor is sold individually.
