AEM Universal Wideband UEGO Sensor with Stainless Manifold Bung Install Kit

AEM?s 4-Channel Wideband Air/Fuel UEGO Controller allows users to simultaneously monitor individual cylinder Air/Fuel Ratios (AFR) on up to four cylinders, and can monitor up to 8 individual cylinders with the addition of a second unit (up to 16 cylinders with four controllers). The AEM 4-Channel Wideband Air/Fuel UEGO Controller can increase both engine performance and reliability. It is the most affordable multi-channel air/fuel controller available, and is a must for anyone using an engine management system or data logger to monitor and/or tune individual cylinder AFR. *UNMATCHED CONTENT AND ACCURACY* AEM has engineered several features into the 4-Channel Wideband UEGO Controller that provide unmatched accuracy and feature content: *Back Pressure Compensation for Accurate, Pre-Turbo, Individual-Runner AFR Readings* Eliminate the need for averaged post-turbo AFR readings. Sensors can be mounted pre-turbo by using AEM?s optional Exhaust Back Pressure Compensation Kit (PN#30-2064). Thi
