30-0300 X-Series Wideband UEGO AFR Sensor Controller Gauge

No issues, straight forward install. 17 sierra

Perfect original item

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.

Highly recommend this product, I installed on 95 firebird

68 VW Bug with dual IDF carbs. Tuning by ear and RPM only gets you set at idle. But what does your mixture look like at high load when you get into the main jets? I don't have it permanently mounted. I just ran the cable into the car so I could see it while driving. It was nice to confirm that at WOT I was running a touch rich. Perfect. Then I could take the O2 sensor out of the exhaust, put the bung plug back in, and save the sensor for the next time I need to tune. I did previously weld in an 02 bung in my exhaust. I knew I would be running this at some point. Most muffler shops will do that for you for a few bucks.

Authentic sensor and security sealed from AEM. Comes with authentic FAE sensor & paper warranty information.

Gauge works great but 02 sensor went bad after 2 uses and isnt covered under warrant recommend gettin the actal bosch o2 sensor

Easy install. functionality's is excellent great readings. very durable. great value for the money excellent display. Easy adjustment for different readings.

Tengo 2 meses de uso y está funcionando perfectamente

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.

Spedizione molto veloce, arriva tutto come si presenta in foto

Entrega súper rápida. Probada y es súper sensible, descubrí las fugas en el escape gracias a ella. A ver cuánto dura funcionando...
