Which O2 sensor to buy??

[gschotland]

I recommend investing in an oxygen sensor wrench in order to avoid the possibility of an open end slipping off, resulting in a smashed finger or worse. I used it with a long handle ratchet with a head that could be vertically angled. Being able to use a cheater bar for added torque was a big help. A couple of mine were really tough to remove.

All major auto parts stores stock O2 sensor wrenches for $10-$15, but I picked one up on fleabay, $9.95 delivered. Very well worth it IMO.

With the right tools and sensors with OEM plugs this is a very easy job.

BTW, ********************************AZ's got Bosch with the plug for $121 each. The ones I got from MaxSpeed were Walker (I believe), another big name in O2 sensors.
