Stay away from Bosch. Denso direct fit would be my recommendation. Rockauto sells them for a good price.

You can look up the OEM part number on OEMAcuraparts.com for the downstream/upstream sensor and cross reference that with the part numbers on RockAuto's site. O2 sensors are found under the Emissions submenu on RA's website.

Put it in with a bit, a very small drop, of anti-sieze on only the threads. You'll probly need a giant wrench to pull it, this should make it easier if you ever have a problem again.
