Good product
Worked great on my holley terminator x and it's good price. I killed em when I went to a 16 volt battery but for a 12 volt car highly recommend

A bit slow on my innovate afr gauge. But for the value it’s not bad.

Not Impressed
Thought I'd try this O2 sensor with my Holley Sniper EFI, bad choice. It looks identical to the Bosch I removed, but it died in less than 1 mile. I might have gotten a bad sensor, but not worth the risk of trying it a second time. I'll pay the extra and stay with Bosch.

Looks good.
I cannot speak to technical performance or longevity on this. I did compare it physically to the actual name brand it replaces (*B* 17025). It looks right. It has the 6 pin connector but uses only 5 wires just like the original. The shape of the connector appears correct. The wires are protected just as on the original. One exception is right near the electrical connector - they are exposed for about a half inch. I plan to wrap this before use to protect these small gauge wires. The overall length is also correct. The threads do NOT appear to be coated with anti-seize compound like the original and that is definitely needed before installation. The price is *much* lower than the name brand. If this O2 sensor proves to send accurate data, it would be a really good value. This one is going in my trunk for emergencies.
