Product Details

NTK Direct Fit Oxygen Sensor 25192 is part of NTK’s Direct Fit Oxygen Sensor line, which focuses on OE-style replacement coverage and application-specific fitment. NTK is a major original equipment oxygen sensor manufacturer, and this sensor reflects that background with a specific-fit design intended to match the original mounting and electrical layout. For buyers searching for a downstream oxygen sensor for Suzuki Forenza 2006, 2007, or 2008 models, part number 25192 provides a direct replacement path. This part cross-references Bosch 15799 for the same application.

What It Helps Address

• Check engine light related to downstream oxygen sensor faults
• Incorrect oxygen sensor signal readings
• Emissions system inspection failures tied to sensor performance
• Rough fuel control caused by a worn or inaccurate sensor
• Replacement needs for a threaded, heated OE-style sensor

Installation Notes and Tips

Verify the connector style, wire count, and downstream location before installation. Confirm the 18 mm threaded mounting point matches the original sensor location on the vehicle. For 2006-2008 Suzuki Forenza oxygen sensor replacement, compare the old sensor’s harness length and routing to ensure proper fitment. Use the vehicle’s service information for torque and connector handling procedures.

Quality Assurance

NTK manufactures oxygen sensors with extensive production testing to help ensure quality and reliability that meet or exceed OE specifications. The brand’s OE manufacturing background and application-specific coverage support consistent fit, form, and function for direct replacement service.
