Beware - Fake item
The gauge came in a rather scruffy but genuine looking AEM box. However the gauge and sensor included were not genuine - The gauge was not even marked as AEM, and the sensor was not a Bosch unit. Have requested refund.

Très bon produit : précis et simple d'installation
J'ai acheté cette sonde Lambda pour remplacer mon ancienne INNOVATE qui ne fonctionnait plus convenablement. Le fait que ce soit le manomètre qui centralise le faisceau d'alimentation et celui de la sonde lambda rend l'installation simple. L'appareil gère tout seul son rétroéclairage donc deux connexions en moins. Le manomètre étant peu profond il peut s'installer même là où il n'y a pas beaucoup d'espace. Mais surtout ce que j'ai apprécié c'est la rapidité de mise en service à démarrage, le calibrage déjà réalisé en usine, la précision de lecture et la fiabilité du produit.

It’s the real deal 👍🏼
I’m writing this for people on the fence about whether it is the real AEM gauge/sensor or not. It is, I went to AEM’s website and compared the part numbers and pics and it is exactly the same. I installed it per instructions and warnings and it is working perfectly. It’s a good deal and a great product.
