AEM's Analog Face Gauges offer quick and smooth needle movement that is easy to read in daylight and night. Each gauge offers a swept are of 320 degrees, resulting is the most resolution possible. All AEM analog gauges offer seven backlight colors and two bezels (silver and black) to best match the interior of your vehicle. All wiring and sensors are included for easy installation.   

If you are using a Water/Methanol Injection System and want to know exactly how much fluid you are actually injecting into your engine, the AEM Water/Methanol Flow Gauge is a must. It replaces the "dummy light" with actual data displayed on a smooth moving needle-type gauge that allows you to accurately monitor the status of your injection system in real time. The gauge kit includes a precision flow sensor and fittings for use with 1/4" OD nylon tubing, so the AEM Water/Methanol Flow Gauge fits most Water/Methanol injection kits on the market today.

For best results the 0-500CC Flow Gauge (AEM part# 30-5141) should be used on Water/Methanol kits injecting up at least 200 cc/min and is ideal for those with the AEM Water/Methanol kit using the medium sized nozzle (315 cc/min). If you are using the largest (550 cc/min) or multiple AEM nozzles, we suggest the 0-1000CC Flow Gauge (AEM part# 30-5142).
