AEM 30-4110 FITS: Digital Wideband UEGO Gauge GaugesAEM'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. NOTE: The 30 4100 Wideband UEGO Gauge Controller that uses the 4. 2 LSU sensor will be superseded to the 30 4110 Wideband UEGO Gauge Controller that uses the 4. 9 LSU sensor

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. NOTE: The 30-4100 Wideband UEGO Gauge Controller that uses the 4.2 LSU sensor will be superseded to the 30-4110 Wideband UEGO Gauge Controller that uses the 4.9 LSU sensor in August 2014. Instructions for the 30-4100 will still be available in the Instructions tab after this change. 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. WHAT IS FREE-AIR CALIBRATION? Some of our competitors require that you frequently perform a free-air calibration procedure to calibrate their O2 sensors. This process involves removing the sensor from the bung while still connected to the controller device, then waving the sensor in the air so it can read atmospheric O2 levels. We use 4.9 LSU sensors in our wideband controllers. Our sensors are individually laboratory-calibrated and never require free air calibration!

Comfortable but smaller than a standard pillow.
Size: Standard (Medium)
The pillow is bit smaller than standard length wise. It takes a while for the smell to go away. Very comfortable pillow.

Remarkable and impressive pillow
Size: Standard (Medium)
The pillow came quickly and was what was expected. After 6 months of chronic neck pain, one night on this pillow has made a world of difference. Please buy one of these if you are on the fence. They are wonderful. Highly recommend.

Not any more breathable than other pillows
Size: Standard (Medium)
I got this in hopes that it would be cooler than other pillows but it seems to hold the same amount of heat. Additionally, as a side-sleeper, it is too thick for me. It is however pretty comfy and seems to be made out of quality material. As other reviews stated, it was smelly at first but that went away within a week.

Great pillow
Size: Standard (Medium)
I love latex pillows. They are bouncy but yet soft. This is my second one. This one is the medium and my first soft. I use soft on top laying watching tv and sleep with medium. No neck pain at all. I have always loved these from years ago. Will always use these only.
