The NGK Powerdex AFX is replaced by the Ballenger Motorsports AFR500 or the NTK AFRM.

The NGK Powerdex AFX has been discontinued by NGK. The NGK Powerdex AFX is replaced by the Ballenger Motorsports AFR500 or the NTK AFRM. The Ballenger Motorsports AFR500 works with the same sensors, wiring, offers the same reliability and is a direct successor to the NGK Powerdex AFX. The NTK AFRM is a new product offering with a completely new sensor which has no replacement availability as of July, 2014.

NTK has released the NTK AFRM – Air Fuel Ratio Monitor Kit – Wideband O2 – PN 96604 – w/ NTK Sensor to replace the NGK Powerdex AFX.  With a smaller display, simpler calibration, improved diagnostics, increased sensing range, and new sensors, the improvements are significant.

Despite the improvements, the cost remains the same as the NGK Powerdex AFX!
