AEM's part number 30-4110NS Wideband UEGO air/fuel ratio Controller Gauge is sold without a wideband sensor. This allows users to source a Bosch 4.9LSU sensor separately to potentially save money.

AEM’s legendary Digital Wideband O2 AFR UEGO Gauge is a wideband UEGO air/fuel ratio controller (AFR) and gauge in one. It unites accuracy, speed and control with an easy to read, digital LED display and sweeping LED “needle” that changes colors as AFR changes from rich to lean.

AEM tested many sensors with the 30-4110NS, including popular inexpensive knockoff sensors, and determined that only the following sensors will deliver reliable performance:

Using the above sensors ensures that the factory sensor calibration is accurate and that the controller performs optimally. The use of any non-approved sensor may affect the controller’s operation, and will void the warranty of the 30-4110NS.

WHAT IS A WIDEBAND UEGO AIR/FUEL CONTROLLER?
AEM's Wideband UEGO (Universal Exhaust Gas Oxygen, pronounced “You-Way-Go”) Controllers are powerful, cost effective tuning tools that allow users to accurately monitor the Air/Fuel Ratio (AFR) of their engine.

WHY USE A WIDEBAND AIR/FUEL CONTROLLER?
Accurate AFR data is critical when tuning an engine. Running rich (very low air/fuel ratio, excessive fuel) can cause a loss in power, while running too lean (very high air/fuel ratio, not enough fuel) may result in serious engine damage. Using a wideband air/fuel controller during the tuning process allows you to monitor AFR and adjust tuning parameters to optimize them for maximum power and efficiency. AEM has a comprehensive line of highly accurate, reliable wideband air/fuel controllers that can help ensure your vehicle is optimally tuned.

Good looks but cheap fabric
Size: Large, Color: Light Blue
The sizing is about right, but the fabric is really cheap, flimsy and rough. Disappointed and this is going back

Nice!
Size: Medium, Color: Bright Blue
My husband loves these. He’s got black, navy, bright blue, burgundy, grey…. and I’m sure I may be missing some! They hold up nicely after repeated washings in cold water in the machine and I always hang to dry. For golf they are fabulous because they are non constricting and comfortable while playing in the hot Florida sun which he does on a daily basis. They run very true to size….he takes his usual medium and they fit perfectly. Highly recommend!

I am thoroughly impressed with this Amazon Essentials white shirt. For the price, the quality is outstanding. The fabric feels soft, breathable, and has a good weight to it

Nice shirt, great price.
Fit Type: Regular Fit, Color: White, Size: Medium
Worn it twice and I find it very comfortable. I wear it outside and casually to protect my arms and neck from the sun and find it more comfortable than a long sleeve t-shirt. The price is comparable. If I was to wear it to the office it would have to be ironed. I bought one shirt to try it and I will be buying more.

Nice shirt!
Fit Type: Regular Fit, Color: White, Size: X-Large
I added one of these shirts to another order just to see if they were any good. I was pleasantly surprised by the quality. It fits perfectly and looks pretty nice for a low cost casual dress shirt. Materials seem decent quality. Comfortable, soft fabric. Didn’t shrink too much in the washer and dryer. We’ll see how it holds up long term but so far so good
