[HWYSTR455]

The early Innovative wideband tools used the NTK sensor, that's why they were so expensive.

The bosch don't read very well outside of a narrow range, but for most purposes, they do fine in general automotive use. They have issues, just to say. (would have to lookup what that range is, but it's something like 10-22, and the NTK is like 5-35 or something)

Any of the Holley ecu aside from the 'entry level' ones accept NTKs. Connectors are diff because there's more wires I believe, depending, and the ecu has a controller built in for each type.

If you're doing race gas or E85, you want the NTK sensor. They recover from extreme conditions (like a flood) and live longer too.
