Actually it means "No Longer Available". If you see a hose listed like this email me and I may be able to get you something that is comparable. It won't be exact, but it will work. Ken

I'm guessing by "NLA" you're meaning from VW,

Ken Wilford November 18, 2015

I did leave that out. You can source that from your local auto parts store. The hose is 5/8" heater hose from the rear heater T all the way to the front. Then there are two preformed hoses at the front heater core which we have in stock. Here are links to them: They are $45 each. Let me know if we can help you further.

I think you left out the hoses that run from the rear heater core to the front heater core and back again. see Bentley 19.10 I am looking for a replacement of these hoses as the ones I have were implemented backwards by the PO and result in warm air contantly flowing onto my feet.
