When converting your Porsche 911 or 930 Turbo to electronic fuel injection (EFI), you will require an accurate way of measuring cylinder head temperatures for the computer's "coolant temperature" input signal.  

TurboKraft's kit offers a simple way of installing a factory cylinder head temperature sensor to your engine without having to remove and machine the cylinder head.  

The set includes a new Bosch sensor assembly, billet mounting adapter, and instructions.

NOTE:  both sensors are genuine Bosch but the large price difference is because of the age of the part.
* The 10mm sensor is original to the 1984-89 911Carrera 3.2L, and is now only available from Porsche dealerships.  We only recommend this sensor if you are using original 1984-89 Carrera cylinder heads in your EFI conversion (no TK adapter required).  
* The 12mm sensor is from the 1995-98 911 (993) model, and is still offered directly from Bosch, no dealership markup.  This is the sensor we recommend for almost all applications.

The matching white connector kit is available for the 12mm (993) sensor.
