The APSX Wideband O2 is the newest and one of the best wideband gauges on the market. We've recently tested this gauge outside of our wideband shootout, where the APSX Wideband O2 matches the performance of far more expensive wideband choices. In fact in a direct head to head comparison between the APSX Wideband O2 and the AEM UEGO, we found little to no difference.

This wideband gauge from APSX combines excellent response time and accuracy, and it's paired to the Bosch LSU4.2 oxygen sensor. Built with high quality components, the APSX Wideband O2 sensor returns air fuel ratios in as little as 30 ms.
Together with the anti-glare lens, the APSX Wideband O2 gauge is the cheapest wideband gauge that works as well as the big boys. Designed for accurate reading and fast response, the APSX Wideband O2 gauge is simply one of the best wideband gauges on the market today.
