 Correct P/N for 1999 Avalon Calif Bank 1/ Sensor 1 (Rear Bank A/FUpstream Sensor)
Rockauto.com seems to list one part number for both banks. Denso
Aftermarket is the only brand that still has two numbers, but these
two look identical (maybe a generic picture).
Since Denso is the only sensor for this application (the others rebox
the Denso), just get two Densos.
#8946741011 FRONT Passenger Side; Calif
8946741020, 8946741021 FRONT Driver Side; Calif
