Key Features

• Specific-fit oxygen sensor for direct replacement
• Heated sensor design for faster operating temperature
• 4-wire configuration with a 15.2500 wiring harness length
• Threaded mounting with 18.000 thread diameter
• Built for downstream B1S2 oxygen sensor applications
• NTK part number 24242

Product Details

NTK 24242 is part of the Direct Fit Oxygen Sensor line, a product range focused on OE-style replacement coverage for import and domestic vehicles. NTK uses ceramic sensor technology and extensive manufacturing testing to support consistent signal output and reliable operation. For drivers and repair shops servicing an Acura EL or Honda Civic, this sensor provides a direct replacement option for the downstream oxygen sensor location.

This part cross-references Bosch 13534 and DENSO Auto Parts 234-4220 for the same application.

What It Helps Address

• Check engine light related to downstream oxygen sensor faults
• Incorrect air-fuel ratio feedback from a worn sensor
• Emissions test failures tied to oxygen sensor performance
• Rough idle or drivability issues caused by inaccurate exhaust readings
• Slow sensor response in heated oxygen sensor applications

Installation Notes

Verify the vehicle’s downstream B1S2 location before installation. Confirm connector style, thread size, and harness length against the original sensor on the 2004-2005 Acura EL or 2004-2005 Honda Civic. Use proper exhaust sensor removal practices to avoid damaging the bung or wiring.

Quality Assurance

NTK is the oxygen sensor supplier within the NGK family of products and manufactures sensors to meet or exceed OE specifications. Each sensor is tested during production to support quality and dependable operation in real-world emissions control service.
