Not for Ford Transit
I think this would normally be fine, but my Ford Transit did not like it at all - three more codes than the original. Had to go with a Dorman/Motorcraft.

Works as advertised
Perfect replacement for my kids 2012 Ford Focus Titanium. Check engine light indicated that the O2 sensor was bad and holy moly was it right. When we pulled the old one out it was caked in carbon deposits. This one threaded in with no issues and after we cleared the stored code it has worked flawlessly! I would recommend this over other cheaper aftermarket O2 sensors. I would rather pay a bit more and have peace of mind that this will work for the long term.

افضل شراء من مكان موثوق ولديهم ضمان
للأسف تم شراء اثنين من الحساس وواحد منها تعطل بعد 6 اشهر وسبب مشاكل في صرفيه البنزين وريحة الكربون والدعم رفضو استرداد القطعه او استبدالها
