Auto Meter Air Fuel Ratio Gauge - Good Choice?
#1
![Question](https://ls1tech.com/forums/images/icons/icon5.gif)
I am considering this A/F ratio gauge for a permanent installation in my car. I have never owned or used one of these meters before. Back in the day, we used EGT gauges.
Is this gauge a good choice for accuracy and quality?

Unless you just want the round gauge, for that kind of money I would go for a NGK AFX with a NTK sensor. It will be more accurate than what you have linked.

I was not aware that the Autometer a/f gauges were inaccurate. Their stuff is typically exceptional, so I assumed it would be a good choice. Is the NGK the only accurate brand?

Sorry - I didn't mean to insinuate that the autometer WB is inaccurate or junk. Not at all. However, the bosch sensors don't seem to be as robust as the NTK sensors. For a gauge in the car running on unleaded fuel it will be fine and that package has a lot of nice features. There is a ton of info on all the wideband options through the search.

I just went through the same decision, there's a good discussion on the forced induction forum about installing gauges but gets into details on sensors, etc. I ended up ordering Prosports' new Evo gauges - they use the Bosch 4.9 sensor. They don't have the Evo on their site yet but if you call they can send a picture; really good looking, won some awards at the auto show in Vegas recently.
