No it's not, I ran mine for 3-4 months n/a with no heatsink. I did add one prior to fitting my supercharger though...

I made the same thing in alum. while I had the transmission dropped....fixed my "heat" error after boosted runs!

ian't Alui's melting point around 500deg? exhaust gasses can hit double that?

Unlikely they'll be that high that far down and OUTSIDE the pipe. The purpose of the heatsink is to shield the body of the sensor from extreme heat radiated from the pipe the sensor is installed in. Not the actual exhaust gasses themselves.

~650°c

good thing it's not inside the exhaust

I know the purpose, I just figured if the exhaust temps inside were topping 1000C then outside and a foot away could easily be half that

bringing back something from the dead, but where are you guys getting copper for a heat sink?

copper transmits heat faster than aluminium, but it's harder to find. Aluminum sheets are pretty easy to get at the hardware store and in this application it will work 97% as well.

just use aluminum. it's cheap and easy.

If you really want to use copper you can buy a copper pipe coupler. Cut it lengthwise and flatten it out. The coupler fittings are cheap enough and you can get them anywhere. Long as you can cut, flatten and drill it you're good to go.
Saw patsmx5 do that couple months ago.
