Hey guys- I've always heard/ read that there was no O2 sensor besides Mazda OEM that is a direct plug & play for our cars. Just wanted to let everyone know that I just bought a Bosch sensor (part # 12054) from the local auto parts place that plugs right in to our harness, 86-88 N/A's, at least...Do yourself a favor and also get the O2 sensor socket; with a couple of 3/8 extensions it makes changing that rascall a breeze. have fun...

 

Yep. Also do yourself a favor and get some anti-seizing thread compound.
