Then how about shrink tubing? It comes big enough to fit over the sensor.

I'm not sure if shrink tubing comes that large but even if it did I doubt it would have much insulating value as thin as it is. I thought about trying to find a piece of foam pipe insulation that size because I hate fiberglass, but as hot as that thing gets it might melt foam insulation so I think unfortunately my best bet for insulation would be a piece of fiberglass pipe wrap held on by a couple zipties. The brass part gets hot enough to boil water and it's right under the exhaust header, so I don't want to put anything flammable or meltable on it.
I'm probably going to wrap it tonight, leave it plugged in overnight, and see if it gains any noticeable heating efficiency. If it survives that is
Edit: This is what I came up with. Not very pretty or permanent, but effective. There is definitely more heat transfer to the block now. The part of the block that the heater screws into is now burning hot for the first time after just a couple minutes, normally it's just warm. There isn't noticable heat radiating off the heater anymore either. I will report back with results in the morning.
