The sensor has a 2 bolt flange on the front. Its huge and takes up all the threads. You'd remember if you had one on yours. lol...



Anyways, I'll be heading back to dipshit schucks tomorrow to check their other boxes. Man I hate that place...



Everytime I say "rx7, 91, turbo model" they go bananas on me... talking about their friends friend that has a "TWIN TURBO RX7!!" and its "SCARY FAST!" ... etc.. etc.. **** I hate dealing with them :(

LOL, it was put in right before the tuner came. I really did not even look at it. Just plopped it in. I do remember one bolt but I don't remember if there were 2 on it.



I can't really pull it and check because the car is 50miles away.

I checked with napa and another store, both same part number as schucks, different o2 sensor.



Thanks schucks! You guys rock! .... ******* idiots.
