Great Product
Installed on 2014 F150. Bosch makes great products. Installed electrical products on multiple vehicles brands and models. My go to electrical component manufacturer. No issues yet.

AEM replacement
To those who are looking for an AEM wideband replacement, this review is for you! This is the exact fit replacement for your failed AEM sensor. The harness is shorter than what came with your wideband, but it is the exact replacement for my X series 30-0300. Works perfectly and is able to be read by my gauge and ECU with no errors. Stock up on a few before prices go up and never have to worry again.

Faulty part. Customer service is does not assist in anyway
Part was faulty. Caused my car to misfire and new codes popped up for one faulty sensor. When I tried to reach out to customer service they were dismissive, unhelpful, and implied it was somehow my mechanics fault. Do not recommend you taking the risk of buying, and running into the same issue.

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
