AEM X-Series Water/Methanol & Boost Pressure Kit
P65 Warning WARNING: Cancer and Reproductive Harm - www.P65warnings.ca.gov



AEM's gauges are among the best in the industry, and we've put these together into one convenient kit, featuring AEM's X-Series digital gauges for air/fuel ratio and boost pressure. This kit includes:

  • 30-3301 | Water / Methanol Injection Kit for Diesel Engines
  • 30-0308 | X-Series 0-10 BAR / 0-150 PSI Boost Pressure Digital Gauge


Water/methanol injection (WMI) systems reduce air inlet temps and enhance combustion efficiency on turbo Diesel applications, which allows an engine to deliver more power with less effort. Water/methanol injection also offers a host of benefits that promote engine longevity, including the reduction of carbon deposits left by a Diesel’s exhaust gas recirculation (EGR) system. AEM’s Water/Methanol Injection Systems for turbo Diesel trucks and SUVs utilize the most robust hardware combined with more advanced features than any other comparably priced water/methanol injection system.


Visual improvements include a bright center LED display that is 87% larger than AEM's original digital gauges and provides better readability. A sweeping green LED “needle” lines the edge of the gauge face for quick reference. A 33% overall increase in the gauge face display makes it easier to see at a glance.

Despite the larger display, X-Series Gauges are contained in a standard 2-1/16th-inch (52mm) diameter housing for mounting in a standard gauge pod. Thanks to an advanced single board design, X-Series Gauges have an incredibly slim overall depth of under 0.825”, with a cup depth of only 0.200.” This shallow cup depth allows X-Series Digital Gauges to be mounted practically anywhere.

X-Series Digital Gauges include new technological features that make them easier to use. Two buttons on the faceplate deliver programmability for peak/recall, standard or metric center LED readout and sweeping LED needle, and user-selectable threshold warnings. The gauges are AEMnet CAN-bus enabled, so they can be daisy chained together for use with the Infinity ECU, Series 2 EMS, AQ-1 Data Logger, or 3rd party EMS or logger that accepts AEMnet. 0-5V analog outputs are also included for inputting into data loggers and engine management systems.

TSP is proud to offer best-in-class products from AEM!
