Exact replacement
My 2003 Toyota Highlander with 180,000 miles finally killed one of the O2 sensors and rather than spend $150+ for a name brand one, I figured this would work fine. Turned out to be the case. Side by side they almost look the same and the CEL turned off as soon as the sensor was replaced.Great value and functionality.
