Why you need a CHT gauge?

If you drive an air cooled or in fact any vehicle this CHT gauge will tell you a lot about the state of tune of your engine. Air cooled vehicles especially with stock fuel injection, have a tendency to run hot. Overheating an air cooled engine will often result in damage to the cylinder head valve seats, the so-called "dropped seat" syndrome. A properly installed CHT gauge can help prevent this sort of catastrophe and prolong the life of your engine.

What is a CHT Gauge?

A Cylinder Head Temperature gauge is the missing gauge on any air-cooled vehicle. Most vehicles these days are water-cooled, and every water-cooled vehicle has a vague temperature gauge on the dash which shows the temperature of the engine coolant. You have a warning that the engine may be overheating when your temp gauge heads towards the red but that's all. With this CHT gauge you can accurately measure the temperature to the decimal point up to 1300c or 2308f so you know exactly what your temps are.

Since air-cooled vehicles like vintage VW's and Porsche's etc do not have any coolant inside the engine, we measure the engine heat by reading the temperature of the cylinder head in the spark plug area via a sensor. This area of the head gets very hot and is an excellent indicator of the operating parameters of the engine as a whole.

The CHT gauge kits consist of a sensor and the gauge itself. The CHT sensor is attached to a ring terminal typically placed under the #3 spark plug.

This temperature gauge measures in both Celsius and Fahrenheit:

Celsius from -200c to +1300c.

Fahrenheit from -328f to +2308f

Specification

Gauge Dimensions: 79mm x 43mm x 25mm.

Clear 4 Digit RED LED Readout. Green and Blue LED also available please see my other listings.
12v DC connection.
Fast Response time: 500 msec.
Temp Range: Celsius from -200c to +1300c Fahrenheit from -328f to +2308f
