Review: Works great for on a budget! - Been working spot on for over a year no issues. Only think I can say compared to the authentic AEM gauge is that this one responds just a little slower but is still accurate.
Review: Great for the price@ - After buying expensive wideband gauges, then finding these I figured it was worth a try. Since that first try I've bought 3 or 4 of them for different vehicles. Only had an issue with a sensor on one I purchased. Messaged the company and instead of just sending me a new sensor, they sent a whole new gauge kit within 2 days. Pretty solid product with great customer service.

## Questions & Answers

**Q: Is this gauge waterproof?**
A: no

**Q: What is the wiring diagram for the 6 wire 02 sensor that is included? I want to hook up to a 4 wire bosch 02 sensor instead.**
A: It has instructions for how to wire the gauge into the wires from the O2 plug. But the plugs are standardized, so you shouldn’t need to rewire it. Just plug it in.
