Review on 🔧 Bang4buck 4 Packs 02 O2 Replacement Oxygen Sensors- Part Number 15717 for 2003 Ford Mercury Lincoln Aviator 02-04 Aston Martin by Joseph Hill

Also (as I've noticed many have mentioned) the tabs don't line up at all on the front sensors and there is only one on the secondary sensors, I just cut them off after me have verified the correct wiring order, which matches the way they should be connected to the lock when installed. The secondary worked fine but the primary didn't work at all. Almost immediately I got codes saying I didn't have primary O2 sensors. I just needed a new one in the jar so I ordered one. It had no petals, just a bar. I also checked the wiring before installing it and it worked fine, which is good because it's very difficult to install.
