Hello all, I purchased replacement Denso upstream O2 sensors for my 98 SOHC Explorer. The part number listed on the rockauto.com source matched what Denso had listed on their own site (234-4071 and 234-4127). Apparently, wire lengths were significantly shorter than those of the sensors I pulled out. The driver side sensor had the longest wire length. The longer of the Denso sensors (234-4127) barely reached the connector. On the passenger side, the other Denso sensor was short by a few inches. I contacted Denso, they want the original Ford part numbers. Does anyone have these handy (upstream O2 sensors)?

Any similar experiences?
