  • Highly recommended
Works great! Helped me tune my 67 mustang.

  • Not waterproof
Works well, not water proof so if putting in off road car snake it removable or cover it when you wash.

  • Gauge works just right.
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. ... show more

  • Superior Quality Simple install
Totally satisfied I have a supercharged ls swapped 76 c10 and been trying to get the tune dialed in and this gauge lets me know exactly where I’m at after getting my bung welded in install was quick and painless great instructions would love to get more gauges from AEM when the budget allows

  • Great gauge, well worth the price
Easy to install, reacts nearly instantly, instructions are well-written and exhaustive. I have this feeding the AFR input for a Megasquirt PNP2 controller and they are a happy couple. The hundredths place is a nice touch. I have this gauge mounted to my steering wheel column and I can roughly gauge my AFR while watching the road during white-knuckle pulls with the bright scrolling colored LEDs. ... show more

  • ???
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.

  • The gauge is great
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. ... show more
