The 9 Best Wideband Gauges
This wiki has been updated 4 times since it was first published in November of 2018. If you're driving a high-performance vehicle, you need to keep an eye on your fuel to air ratio in a wider range and with more accuracy than most factory-provided, narrow band systems can offer. That's where a good wideband gauge comes in. Many of the options on our list come complete with sensors and installation kits, and we've ranked them here by their speed, precision, ease of use, and style. When users buy our independently chosen editorial picks, we may earn commissions to help fund the Wiki. Skip to the best wideband gauge on Amazon.

There are some less expensive possibilities on the market, but the quality difference seems too high, making any potential budget options insufficient.
