A wideband O2 sensor is a must have for your performance car! It allows you to know the air fuel ratio which gives you an idea of how the engine is running.

In this video I will be showing you how to do a basic install of the AEM X-Series 30-0300. We will go over why we need a wideband O2, gauge placement on the dash, fishing wires, routing wires, welding bung, and basic wiring. Stay tuned for my megasquirt videos where we will learn how to use the analog 5V input for auto tune and O2 feedback (closed loop).
