Accurate Information
The NGK AFX Air Fuel Ratio Monitor is the most affordable “true” wideband technology to date. Many low-cost air-fuel ratio monitors do not use wideband sensors; they simply manipulate a standard narrow-band oxygen sensor signal with rough inaccurate data resulting in only marginal success. The NGK AFX Air Fuel Ratio Monitor reads air fuel ratio (AFR) values from 9.0 to 16.0 with a resolution of 0.1.
True Wideband Technology
The NGK AFX is a true air/fuel monitor that senses exhaust oxygen, carbon monoxide, hydrogen, and hydrocarbons in the exhaust and calculates real time air fuel ratio (AFR). Air Fuel Ratio is a crucial parameter that dictates horsepower and engine performance. Performance enthusiasts and tuners can use Air Fuel Ratio information to make adjustments to the fuel delivery system (carburetor, fuel injection) to help achieve the maximum horsepower available from their engine. The AFX is compatible with both Bosch LSU and NTK UEGO (wideband) sensors without any changes in hardware or programming and offers superb accuracy (comparable to some laboratory grade systems).
Cost Effective
Traditionally these types of tools commanded price tags in the thousands of dollars putting them out of reach for most enthusiasts and amateur/grassroots racers. NGK’s advances in technology have made this highly accurate tool affordable.
Experience
NGK-NTK is the world leader in exhaust gas sensors and sensor related technology. They supply OEM oxygen sensor technology to a huge range of Asian, European, and domestic auto manufacturers.
Analog Compatible
The NGK AFX has a 0 ~ 5V, linear analog output for AFR that can be used as an input to an engine controller, data acquisition system, or analog gauge with 0 to 5 volt input.
Complete Wideband O2 Kit
The Air Fuel Ratio Monitor Kit is a complete wideband O2 kit. This package comes:
* Digital display controller (~3.4in x 2.7in x 1.3in)
* 13′ wiring harness
* Wideband oxygen sensor
* Exhaust boss & plug
* Comprehensive air-fuel ratio tuning manual
This is all you need to accurately read air fuel ratio values.
Inexpensive shipping
At Ballenger Motorsports, we know how annoying it is to see companies skim off the top on shipping. It’s always insulting when you feel you got a good deal only to find that it cost $50 to ship something that cost $15 to ship. We don’t make money on shipping and we don’t
overcharge on shipping.
If you have any questions, please feel free to contact Ballenger Motorsports at sales@bmotorsports.com.

About this sensor: The Bosch UEGO Sensor with NTK/NGK Connector is the recommended replacement sensor for the NGK Powerdex AFX and is the same sensor that NGK packages with the Powerdex AFX. This wideband o2 sensor combines low cost with high accuracy and long sensor life. This excellent combination is exactly why NGK chose this sensor to ship with the NGK Powerdex AFX! This sensor has been modified by adding the NTK/NGK connector to work with the NGK Powerdex AFX and will not work in any other application.

About this sensor: The NTK/NGK UEGO Sensor is a higher cost replacement sensor for the NGK Powerdex AFX. Some tuners swear by this sensor; that this sensor lasts longer and maintains greater accuracy over the life of the sensor. While the Bosch UEGO Sensor with NTK/NGK Connector is still the recommended replacement sensor for the NGK Powerdex AFX, this sensor provides the best accuracy and sensor life available. This sensor can be used in OEM replacement applications and other wideband systems using the NTK/NGK wideband o2 sensor.

About this sensor: This wideband o2 sensor combines low cost with high accuracy and long sensor life. This excellent combination is exactly why NGK chose this sensor to ship with the NGK Powerdex AFX! This sensor has the original Bosch/VW connector and has NOT been modified. This sensor will work in OEM replacement applications and other wideband systems using the Bosch LSU 4.2 sensor. This sensor will NOT WORK WITH THE NGK Powerdex AFX, you must choose the Bosch UEGO Sensor with NTK/NGK Connector (at top of page) or purchase the NTK/NGK Connector Kit to work with the NGK Powerdex AFX.
