As you may already know, the NGK Powerdex AFX – Air Fuel Ratio Monitor Kit has been replaced by the NTK AFRM – Air Fuel Ratio Monitor . Ballenger Motorsports supported and heavily marketed the NGK Powerdex AFX since its introduction and we looked forward to its successor. NTK chose to branch into a new product direction with the NTK AFRM, breaking compatibility with existing Bosch & NTK sensor products as well as any cross-compatibility with the Powerdex AFX wiring & installation.
Our customers have asked for a continuation of the AFX and we are offering a direct solution. Ballenger Motorsports is releasing the AFR500 as a direct successor to the AFX! The AFR500 works with the same sensors, wiring, and offers the same reliability. We also plan to offer some additional options which were previously unavailable such as a shorter harness length and additional sensor options. We will concurrently sell and support the NTK AFRM.
At $299 retail, the base AFR500 will include the following:
Large, bright digital display controller (~3.4in x 2.7in x 1.3in)
13 ft wiring harness with sealed connections
Bosch LSU 4.2 wideband oxygen sensor
Weld in exhaust bung & plug
Installation, troubleshooting & tuning manual
- NTK production grade sensor (+$50)
- NTK calibration grade sensor (+$150)
- NTK lab grade sensor (+$450)
- 7ft wiring harness (+$10)

To address some questions, below is a quick Q&A:
Q. Why offer the NTK AFRM and the AFR500?
A. The NTK AFRM is a new architecture using a new sensor. Many of our customers want to use the well proven NTK and Bosch sensors with the known reliability and excellent track record that the prior system offered. To meet this need, we released the AFR500. Anyone familiar with the old offering will immediately recognize the function and capabilities of the AFR500.
Q. Should I get an NTK AFRM or an AFR500?
A. The AFR500 has a long, proven track record providing accuracy, reliability & precision of systems typically costing $1500 or more. The AFR500 also works with several sensor options while the NTK AFRM only works with a single sensor type with no replacement available as of July, 2014. The NTK AFRM was designed by a different group and has yet to establish a following.
Q. Can you explain these NTK sensor options?
A. The NTK sensors come with varying levels of capability based on their intended usage. Most systems will simply offer an NTK sensor as a single option which can be misleading when you are comparing lab grade equipment at high cost to a system using the lowest cost sensor in the same family. We have chosen to provide customers with a full range of offerings.
Q. Is the NTK sensor better than the Bosch sensor?
A. In some cases, yes. For leaded fuel, for periodic moisture, or contaminant exposure the NTK sensor family clearly demonstrates superior performance. Many tuners have reported thousands of dyno hours on NTK sensors with leaded fuel while the Bosch sensors die quickly with lead. No sensor is immune from poor tuning however and a rich misfiring and exhaust backfiring engine can damage even the most expensive sensor in a matter of minutes. For a casual street user on pump gas, there is a less discernible advantage for the higher cost sensors.
