O2 gauge and sensor.

There are literally dozens of sensor kits and gauges. I used a wideband O2 sensor many years ago where you had to solder your own circuit board. Now most Performance car shops can sell a sensor and gauge...and 14mm Nut to weld onto your exhaust. Locally Repco etc

A/F is interesting to see though you cannot do much about it in a 912....

"can anyone tell me where I can purchase a Thermostasis 205F oil thermostat."

Have you asked yourself - why do I want one? 

May be highly desirable, even essential, in countries with very cold climates - NZ????

I have an unused one (never had oil through it) that I removed from a partially built home build that I purchased - not sure of the heat range. What identifies a 96C variant, from its siblings?

I have one I bought several years ago and ended up not using it.  I had planned to fly in the winter but it is easier to leave it in the hangar when it gets cold.  If you are interested I could send you some pictures and would give you a good price.

Hello Bill,

Yes I would be very interested in buying the thermostat from you.  

Is it the 205 degrees F version?

I am unsure of the protocol but if allowed under the rules of the forum I could give you my email and we could go from there.

I look forward to your reply.

Thermostasis is very helpful even in NZ ! I have found it saves a lot of time in winter on warmup and helps keep the oil up to temp at altitude in winter.

Not uncommon to be near freezing on the ground here and well below at height in the winter. I have seen -5 deg C on the ground and -20C at height....

In summer not needed but the systems do not seem to impede oil flow at all..
