A black bezel and black dual-faced faceplate for air\/fuel and Lambda are included, and an optional silver bezel with white dual-faced air\/fuel and Lambda faceplate is available (PN 30-0300-ACC, sold separately). An Auto Dimming feature is included. Locking connectors ensure a positive connection between the harnesses and gauge and a new single board design adds to the gauge's durability.","brand":"AEM","offers":[{"title":"Default Title","offer_id":50783605489969,"sku":"AEM30-0300","price":215.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0837\/7319\/4545\/files\/2f94eb85cadb0b78d694964be88e6514.jpg?v=1741306118"},{"product_id":"aem-x-series-pressure-0-100psi-gauge-kit","title":"AEM X-Series Pressure 0-100psi Gauge Kit","description":"X-Series Digital Gauges include new technological features that make them easier to use.

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  NOTE: The 30-4100 Wideband UEGO Gauge Controller that uses the 4.2 LSU sensor will be superseded to the 30-4110 Wideband UEGO Gauge Controller that uses the 4.9 LSU sensor in August 2014.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!","brand":"AEM","offers":[{"title":"Default Title","offer_id":50783606866225,"sku":"AEM30-4110","price":194.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0837\/7319\/4545\/files\/110330c787e2c6625cdbe32ebadc2648.jpg?v=1741306130"},{"product_id":"aem-52mm-boost-digital-gauge-30-35psi","title":"AEM 52mm Boost Digital Gauge -30-35psi","description":"AEM's digital boost gauges include a 0-5v analog output for use with data loggers and virtually any engine management system, such as the Infinity ECU, Series 2 EMS or AQ-1 Data Logger, making it the perfect solution for users who need to monitor and data log boost at high RPM on tuned engines.
