Want to keep a closer eye on your engine's temperature? This 2-inch (52mm) water temperature gauge is a popular upgrade. It's brand new in the box from AJP Distributors.

It's an electric gauge with an analog needle (red needle) that reads in degrees Fahrenheit. The display is chromed and has a cool LED backlight (multicolored) so you can see it at night. It comes with a 1/8 NPT sensor that you install in your engine's coolant system.

It's a universal fitment part, so it can work in cars, trucks, or even motorcycles with some wiring. The manufacturer part number is GA-029-218-M5. It's considered a performance part and features an illuminated display. Professional installation is highly recommended since you're tapping into the cooling system. A great way to monitor engine health, especially for modified vehicles or older cars where the stock gauge isn't so accurate.
