AEM30-4110NS Digital Wideband UEGO Gauge without Sensor , Black , 6.025 inches

Perfect replacement for my old gage that had some dead LED's. Plug and play and works great!

Fast accurate reliable gauge. Good quality. Great for tuning.

Just so those know, this is just a gauge kit and it doesn't come with an O2 sensor, I ended up buying a Bosch eBay sensor, I paid $29 which is much cheaper than what AEM wants for one and it works just great. Much better way for the person who tries to save a dollar like me.

It came with everything you would expect except the o2 sensor which was something it said it wouldn't come with but all the wiring and gauge are there.

Why did you pick this product vs others?:Worked good but eventually some of the led lights stopped working.

Gauge light number defected. Guess I'll going back to haltech

Recently installed this on my 65 Mustang to help dial in my Edlebrock AVS 2 carburetor. Works very well. Make sure you use the Bosch 17025 Bosch LSU4.9 O2 sensor. I didn't think I would use the data logging facility, but after watching D3Sshooter's video on youtube decided to install the cabling necessary to log the data. Glad I did because now I can graph idle, cruise, and power AFR results. Made tuning easy.

Accurate description, nice looking gauge. Would recommend if you already have a lsu 4.9 sensor.
