AEM Water Temperature Gauge Most stock temperature gauges only have an arbitrary range of temperature. The AEM Water Temp gauge will let you know the exact fluid temperature within 2 degrees. That is important because once your stock gauge shows a rise in temperature you might already be overheating. We have found stock gauges to really only have 3 temperatures - (1) Cold (2) Normal and (3) Too Late!
Don't find out you have been on the edge of overheating and risk a head gasket - get an AEM Water Temp Gauge and know your exact temp.
