We have discussed having this part made in the past and i contacted USP Motorsports, WhanAB to no avail and gruvenparts was open to making a billet/tig weleded aluminum version but it required 20 prepaid orders @ almost $150 apiece:

For other plastic cooling parts; these are available and are the same for the new beetle 1.8T:
1. thermostat cooling flange (check) 034 Motorsports, Eurowise, ECS Tuning, WhanAB and many more cheap ones on ebay. (Works on 1.8T and 2.0L)
2. "y" pipe (check) 42DD and gruvenparts
3. cooling temp sensor cooling flange (not yet reproduced; specifically for the new beetle 1.8T) but WhanAB makes one for the 2.0L, plus a vendor ebay sells them as well.
4. heater core connectors: replacement billet or cast aluminum fittings.
So, there are some parts out there that work or some that could be made to work with add on hose and a t fitting.
