Review on 🔧 Upgraded 2PCS Oxygen O2 Sensor Kit for 2005-2007 Ford Focus 2.0L - Upstream & Downstream by Jim Escobedo

Oxygen sensors still work, but only after a workaround -- The top sensor connector does not match the stock sale on the 2007 Ford Focus, so the workaround was to reconnect it to the original connector connect the discarded sensor. Actually not quite sure which sensor is on top and which is on bottom and if they are interchangeable; Any defined upstream and downstream sensors simply by plugging them into electrical connectors. The sensors themselves appear to be fairly well made and pre-treated with anti-seize. So far they're working well, but there would be more confidence if they were made to the correct connector tolerances.
