Superior Engine Protection. Protect your Mustang’s engine against expensive damages caused by unchecked water or methanol flow with the AEM Electronics Water/Methanol Failsafe Device. This piece of equipment ensures that your car’s injection system works properly. It’s also highly customizable with PC-programmable features (via the included USB cable) for easy customization. In addition, this device’s display and alarm are programmable to make it easier for you to monitor the status of your Mustang’s engine.

For Increased Power and Efficiency. A water or methanol injection system ensures that your engine’s inlet air is cooled to an optimal level. As the injection system cools the intake air stream, it allows for more oxygen to be delivered to the combustion chamber. The result is more fuel to be burned which increases power and efficiency. The AEM Water/Methanol Failsafe Device monitors the flow of water or methanol and sends out certain alarms to alert you on the status of your engine’s injection system.

Data-Driven. This failsafe device includes an internal data logger which records injection and alarm statuses for future reference. It’s also PC programmable via the included USB cable so you can conveniently customize some of its features.

Covered by Warranty. AEM Electronics guarantees that this Water/Methanol Failsafe Device with a 1-year limited warranty is free from defects and low-quality workmanship.
