AEM Digital Wideband UEGO AFR GaugeOur World famous Wideband O2 air fuel ratio UEGO gauge features a digital LED display and sweeping LED 'needle' that changes colors as AFR changes from rich to lean. A 52mm (2 1 16") gauge housing ensures that it will fit in most gauge pods and can be remotely mounted virtually anywhere. All AEM digital gauges feature a 0 5v analog output for use with data loggers and almost any engine management system. Each gauge comes with black and silver bezels

Our World-famous Wideband O2 air/fuel ratio UEGO gauge features a digital LED display and sweeping LED 'needle' that changes colors as AFR changes from rich to lean. A 52mm (2-1/16") gauge housing ensures that it will fit in most gauge pods and can be remotely mounted virtually anywhere. All AEM digital gauges feature a 0-5v analog output for use with data loggers and almost any engine management system. Each gauge comes with black and silver bezels and black and white faceplates for multiple color combinations and a custom look (a black Lambda faceplate and black and white Air/Fuel Ratio faceplates).

The Bosch UEGO sensor gives the controller its speed and accuracy. The Bosch 4.9 LSU sensor used in the 30-4110 AEM Wideband UEGO AFR Controller Gauge has a faster light off time and draws less current than the 4.2 LSU sensor used with AEM’s 30-4100 Wideband UEGO Controller Gauge, which will be superseded to the 30-4110 gauge in August, 2014. The 4.9 LSU sensor features the same fuel compatibility as the 4.2 LSU and NEVER requires free-air calibration when used with AEM’s 30-4110 Wideband UEGO AFR Gauge. The 30-4110’s 4.9 LSU sensor uses a different connector than the connector used with the 4.2 LSU sensors included with the original 30-4100 gauge controller. The sensors are not interchangeable between the two gauge controllers in any way, including changing connectors on the gauges.

The Wideband O2 air/fuel ratio UEGO gauge is a must if you want to maximize your engine's power and safety. When tuning an engine, accurate air/fuel ratio data is critical because running with too rich of an AFR can cause a loss of power, and running a lean AFR can result in serious engine damage. AEM's digital Wideband AFR UEGO gauge can quickly alert you to even a .1 change in air/fuel ratio and provide enough time to shut down an engine before damage occurs.

    OK shoes for the price.
    I wasn't sure about these shoes. They look flimsy and thin, but they are actually pretty comfortable. I wouldn't say these are great for outdoor running or anything, but I wear them around the house and took them on a cruise, and, surprisingly, I walked more in them than in my normal sneakers. They fit fine and are easy to slip on. They are easy to clean, just rinse off. Breathable. They aren't the most attractive shoes I own, but they pass. Would I get them again? Probably. We will see how long they last.

    Definitely a good surprise
    Size: 12.5, Color: A Black
    Absolutely the most comfortable shoes I have ever had. Extremely lightweight true fit. They are very breathable. They are not a running sneaker. They seem to be very durable as I wore them everyday of vacation while walking around Las Vegas. I would definitely buy them again. Very good buy for the price

    Didn't fit my narrow feet, but still excellent shoes at a great low price
    Size: 11, Color: A Black
    These are some of the lightest shoes I've ever seen, but the build quality appears to be excellent. They're tongue-less, like slip-ons, but unlike some, you can adjust the tightness with the laces. The body of the shoe is a mesh-like fabric, which allows good breathability and overall comfort, and the soles are a molded rubbery material with nice treads for grip. I've been wearing a name-brand shoe made very similarly for a couple of years, and these are a very good likeness of them, at a much lower price. I like them because of the light weight and the fabric, which make them feel almost like you're barefoot. Unfortunately for me, I have narrow feet, and these fit more like a D width shoe, with more room in the toe box than I can handle. I'm returning them for that reason. For people with "normal" feet, these make really nice, stylish and comfortable shoes. I don't know how well they would hold up to sports or running, but for walking and day-to-day wear, they're great. I suppose I could grade them down because they don't fit my feet, but I find lots of shoes don't, and many makers use D width as the default for men's shoes. So I'm still rating them as 5 stars.

    In a pinch they're worth it.
    Size: 12, Color: D Grey
    I got the dark gray color. They came exactly as pictured and are decently comfortable but as far as packaging it's very poor. They come in a small plastic bag all squished and deformed so you have to wear them a few times before they take shape again. For the price it's a great buy for some generic work shoes or something, the bottom tread doesn't last long at all though if you're expecting them to last a long time as it will be gone in a week or two if you wear them frequently. Buy them if you don't feel like spending a lot of money on shoes but want a new pair cheap.

    Ladies, don't be afraid. Buy 'em. Trust me
    Size: 9.5, Color: A Black
    My elderly mother adores these. She had to have breathable awesome shoes for post-surgery and these fit the bill (and her feet!) So i got some for me. Whoa. Comfort! And I love the slip-on ease, b/c sometimes I just need to go, go, and go some more. Love them in black, haven't had long enough for durability, but helpful for my mom in her physical therapy and they're holding up to the worst she can do to them.
