FYI, bosch o2 sensors have been known to "not play nice" with GM computers. Stick with Delco o2 sensors if at all possible

what about an ntk (ngk but o2 sensor line)? i have that on my 89 z24 right now and its seemed be be fine for well over a year now.

also, really what is the price difference between a 4 wire and a 3 wire heated o2 sensor, retail price where sharkey and i went today was freakin near 200$ for the 4 wire sensor.

i know for a fact my dads 3 wire o2 sensor cost us 60$ and i now get a better deal at the parts place.

so why so high for the 4 wire? isnt a 3 wire adequate? have there been other tests done / documented on the quality of the signals between a 3 wire and 4 wire sensor?

I don't know where you guys are getting your parts... I bought a 4 wire a few months ago for $30. 3 wire will work just fine too.

I've only heard bad things about bosch parts specifically, so I don't know about other brands. They're probably okay for normal driving, but if you're going to be doing any tuning, I'd try to get Delco.

You can usually get some good deals on ebay..

lol canada the parts are a lil more expensive.

thanks for the fyi, if we cant find any 4 wire i am definetly going to try a 3 wire.
