Replacement Dynon EGT probe source
Can anyone recommend a good (economical) source for high-quality replacement EGT probes for my Dynon?

Aircraft Spruce? I replaced a probe for my EMS-D10 and AC had 'em at a decent price.

If you're not making mistakes, you're probably not making anything

$36 USD straight from Dynon is not economical? Or not high enough quality? Not creating waves, just wondering? I've already replaced one in 75 hours, but consider that just part of the cost of owning and operating... If there are better probes out there, let me know too.

There have been a few reliability issues reported on the forum regarding the Dynon probes. You could try KS Avionics http://www.ksavionics.com/. Their probes are twice as much as the Dynons, though. KS makes their own probes and also for at least one major EFIS/EMS manufacturer. Alcor probes are also good. KS is a very small company and when you call 'em you are talking to someone who knows their stuff.

EI probes
After all my Dynon probes had failed after about 200 hours I replaced them with EI ones. Yes they are about twice the price but if they last the life of the engine as they suggest, they will be cheaper in the long run.
EI made them a custom length and were very helpful.

So all these probes are compatible with the Dynon? They all talk a common language?
It's unclear to me what the correct part number is for the Dynon probe from Spruce. They have this big table... is this the one I want:
EGT, 1-2.25" Hose Clamp PN 10-01169 $38.50 ?
What does the 1-2.25" refer to? The diameter of the exhaust pipe?

Yes, that's the one for Lycoming, and yes, it's the exhaust tube diameter. The Aircraft Spruce website has them for $36.65. http://www.aircraftspruce.com/catalo...clickkey=36099

Ok thanks. The part I posted was from the Aircraft Spruce Canada site - $38.50 in Canadian Dollars.
In the big table on the Spruce site they have columns for various engine configurations. They have L4C which I assume is Lyc 4-Cyl. but they also have L4F. What is that?
I'm tempted to go one more round of Dynon probes, since the more expensive ones seem to be over 90 bucks each (and I also have to pony up for a new oil cooler, and possibly the wheel bearing mod). After my next set of Dynon probes fail, I may consider upgrading.

L4C - Lycoming 4-cylinder Carburated
L4F - Lycoming 4-cylinder Fuel-Injected
