AEM s 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 discontinued 30-4100 Wideband UEGO Controller Gauge. 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, discontinued 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.

Who is AEM?

AEM is an aftermarket company and was founded by John Concialdi and Bob Sullivan back in 1987. The company specializes in providing performance upgrade parts for various automobiles. 

It initially catered to vintage vehicles and modified imports used for street racing. By the early 1990s, it has already established itself as a top modifier and has been chosen by racers day in and day out. 

Today, AEM has remained at the forefront in the industry and has since provided the best air intake products in the market.

Racers Choice

The company rose to success because the cars fitted with their products won actual races. AEM has been a brand synonymous with fast cars and has been used by import racing legends such as Abel Ibarra, Adam Saruwatari, Tony Fuchs, and more.

The Tradition of Continuous Innovation

AEM has always been a pioneer in setting trends when it comes to aftermarket performance parts. They were the first to offer a packaged air induction system. This paved the way for the 'do-it-yourself' upgrade for most import vehicles. 

They also pioneered the design of intake tubes with specific tube lengths and diameter, and coined the phrase Cold Air Intake when they saw the advantage of having cooler air for the engine.

Some other innovations they did were the conical air filters with built-in air horns, dual-chambered intake kits, a unique bypass valve that prevents hydro locking, hybrid induction systems, and electronically tuned air intakes. 

This shows how AEM has always pushed the boundaries of air intake design in search of more horsepower.

Tried and Tested

All of AEM's products are tested by various independent and 3rd party companies and prove that their products produce the power they claimed, which helps them cement their status as industry leaders.
