Package arrived with a smashed up box that has been taped up. Clearly a used item and missing parts. Gauge was just flopping around in the box. Missing thumb screws and bracket to hold the gauge down. Hopefully i get a replacement or my money back.

Only reason I gave it a 4 star instead of a 5 is because it wasn't packed great. The grease from the threads of the sensor was smeared in the box. And also I only bought it from here because with my prime it would be here 2 days from when I purchased it. I bought it immediately because I needed it quick and the next day it said my package may be delayed and my new delivery date was for 3 days later. That part was annoying. The gauge itself looks great. About to install and confirm it works.Some people said they didn't get the white face like the description says but I did get mine.

Read the instructions carefully it is very important. After 2 replacement the gauge works great. I went to the muffler shop and had them weld the bung into the area specified by the instructions (that is very important) ran the wires to the gauge. Don't tighten the gauge to tight even finger tight may be too much. I just barely tightened the nuts and it works great. Dusty and Anthony at AEM were great they helped me out a lot. Great purchase no regrets.

No me gustó que el paquete me llegó sin el kit de cara blanca por lo que en la descripción de la publicación dice que viene incluida y no es así.

I love these wideband gauges by AEM but I will say I hate how quickly the sensors burn out on them, especially if you don’t have it placed into the exhaust at just the right angle. Any kind of moisture will destroy the sensor in no time.. literally like working the first day, second day burnt out.
