Carrier Transicold Kubota V2203-DI Crank Vent Hose Heater Kit.
This kit was designed by Carrier Transicold to combat frozen vent hoses on the Tier 2-V2203DI engines by teeing into the coolant bypass.
That's all I know about the part. Dealer once sold for $150+.
New old stock, the original box has been thrown out due to shelf wear. Will ship repackaged.
