Reviews

I had a failure of my Cylinder #1 EGT Temperature probe recently, I ordered this new one. It took about 2 hours to install properly, and it worked fine on the test flight. In fact, I discovered that this version of the EGT probe is actually built much better than the original was (it seats much better into the exhaust manifold). The electrical parts were of sufficient length for Cylinder #1, but might not have been for others. The wiring was compatible with my current wiring.

OEM probe fits and works perfectly. Nothing better than “plug and play”.

As a commercial airplane and helicopter pilot, I trust Alcor probes over any other probes by far. Just by looking at them you can see how well they are constructed. I had to finally replace this 86255 that was originally installed 21 years ago! Alcor's support and customer service is down right the best there is. They are willing to help you with anything and their engineers are extremely knowledgeable (on everything it seemed like!). If you are searching for your next probe, not matter what application, just choose Alcor and you will not be disappointed. Thank you Aircraft Spruce for a fast, friendly and money saving experience! I will shop again soon!

Q: What is the length of the leads from the probe?

The lead from the probe to the terminals is about 12 inches. You can order 42525 which is a 90" extension lead (this is there shortest extension lead).

Q: Is this Alcor by Tempest EGT/TIT Type K probe a direct replacement for the JPI M-111 probes? I am replacing my second one in two years.

JPI recommends using their type k thermocouple probes with JPI units.

Q: What are the differences between this probe P/N 86255 and P/N 86317?

P/n: 86255 is a grounded probe designed for use with analog indicators, versus p/n: 10-86339 (86317 or 86343) is ungrounded designed to be used with digital indicators.

Q: Is the red lead shorter than the yellow lead on the 86255 probe?

Yes, the red lead is shorter than the yellow lead.
