Wide band O2 sensor tuning kit
If you are shooting for the perfect tune, this wide band 02 sensor and gauge is the perfect set up. This will measure the air fuel ratio from your exhaust. No more guessing or plug reading. This makes life easy. We recommend installing a toggle switch for power, as you will not always need this on, only for tuning. It uses a lot of power. You will need to weld the supplied bung into your exhaust.
