The Ballenger Motorsports AFR500 Air Fuel Ratio Monitor has proven very successful. In a world where cost-cutting reigns supreme, we’ve kept the calibration quality air fuel ratio meter made by ECM going strong. Previously sold as the NGK Powerdex AFX, it was replaced in the NGK/NTK product line due to high cost and low margins despite its popularity. Sometimes quality comes at a price, and we plan to keep offering this high quality product to consumers, dedicated tuners, and industry professionals.

We received frequent requests for updates to the AFR500. The most popular requests were for a lambda display, the Bosch LSU 4.9 sensor, a faster display rate, and a wider measurement range. We are happy to say that we listened and worked diligently to provide the most requested features to our customers with the AFR500v2.

The AFR500v2 is expected to ship in the second week of April and is available for PRE-ORDER now!
