Legit AEM X series AFR gauge assembly with the correct verified sensor as advertised on AEM website.
After reading the different reviews I was still skeptical about ordering. I said what the heck it’s Amazon and if anything looks out of norm back it will go. Well I received it the day after I bought it so less than 24 hours at no extra cost because of prime, and I must say it is the real deal! The security tape was intact all parts packaged like they are supposed to be, I took a picture of the sensor and verified it and all the parts using chat gpt and everything is completely legit.. so all the other people either don’t know what their looking at or they are unable to identify fake from real. If you’re-wanting the new x series so you can dial your AFR in and get the most out of your engine safely then buy this gauge. I promise it’s worth the extra not to have to worry abt a crap sensor. Thank you Amazon another great delivery!

Worth the investment, good quality
Easy to read and understand, good price for this item. It’s connected to Hondata S-300 and hopefully I could get a fuel tech for my b series.

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.
