AEM Performance is state of the art electronics and performance parts. AEM electronics are the finest engineered & highest quality with the best value the industry has to offer. AEM was the first company to incorporate a gauge interface with a wideband air/fuel controller, and we have innovated in this category again with the Wideband Failsafe Device—a combined Wideband controller unit and boost/vacuum gauge that can save your engine if it runs lean.
