If you are shooting for the perfect tune and want the fastest gauge out there, this Rolling Wrench wide band 02 sensor and gauge is the perfect set up. We spent over a year testing and tuning with different manufacturers to find the best quality and fastest sensors out there. There isn’t a better kit on the market, I promise! This will measure the air fuel ratio from your exhaust. No more guessing or plug reading. This makes life easy. The Bosh o2 sensor measures the exhaust gases from the engine and sends a signal to the gauge to tell you exactly what your air fuel ratio (AFR) is in numbers. Use the picture above as a reference for tuning your AFR. You will need to weld the supplied bung into your exhaust unless of course it already has a bung. This gauge even has data logging connections!
