Bosch now makes RX7 OE Oxygen Sensors (connector and all) for $35
 

For those of you who don't already know, the Autozone auto parts chain now carries Bosch origanal equiptment style O2 sensors for $35!! No
more cutting and splicing the wire on those "universal" O2 sensors,
and no more shelling out the big $$$$ to get the Mazda OE sensor (not
that anyone does). Just screw it in, click the connector, and back
in business. I love it. :bigthumb:

If you don't have this parts chain where you live, see if your favorite parts place can order them from Bosch for you.

Later,
