The plastic covered aluminum heater hoses that go from the heat exchangers in the motor to the heater channels in the body of my 2004 Vintage Speedster car are giving up the ghost after almost 19 years. They are basically disintegrating. Anyone know where I can find new replacements for them? Thank you and Happy New Year to all!

I've used that (those) from fan shroud to heater box but used ones with insulation ($25 each) for heater boxes to heater stub stubs.  There is more heat there and the insulation passes the heat on hotter plus decreases engine noise passed into car.

Here's what the OEM ones from donor car were like:

At some point, VS changed the routing for heater hoses.

I think they originally used the 'body tubes', but found that lost a lot of heat and pressure. By 2013 they bypassed the body tubes and connected short lengths of the aluminized hose to the outlets of the heater boxes. That then connected to flexible rubber hose that in turn connected to long lengths of smooth PVC pipes tucked inside the rocker panels. That delivered better pressure and hotter air.

That's what my car has, but I don't know what's on Impala's car.

He said his 'plastic covered aluminum heater hoses' are shot, so I thought he might have the hose in the picture and link I posted above.

@Impala , some photos might help here.

On a few of the older CMC 's that had the short hose out of the exchanger aka heater box to the 1.5" chassis pip,  I routed the heat direct from the exchanger to the vertical fiberglass area below the back seat. The result was super good heat. One another Speedster I routed to carpet area on the lower door jamb that roasted my left hip going down the road.  Lastly, experimented with a 12V high Amp fork lift cab heater using a big alternator and a secondary deep cycle golf cart battery. it worked but don't know the long term result.

Both Mike and my car are CMCs.  CIP2 also has silicon rubber wire reinforced hose.  I used similar to connect under dash to defrost vents. (I didn't get from CIP/CSP so measure size you need)

Update: ordered the hoses from CIP1 as suggested (they got here from Canada in one day!). Of course they slipped right on the heater boxes; but the diameter of the tubes that come from the body of the car is smaller so what I did was to take an old leather belt and cut sections to line those ends of the hoses going to the body and they clamped right up and worked. They look great as compared to what was there. I forgot to take photos but I'll add them later. Thank you guys for your suggestions!

If you want some real heat, bypass the body and go directly into the channels leading to the heater and defroster outlets. Huge difference in airflow and heat. Downside is increased motor noise in the cabin. Add extensions to your curtains to fill the sleeves on the top and get a tie down for the top bow and you have a dry and warm car to drive in the rain. And you will not need a towel for mopping up water.

Car manufacturers are adding artificial noise into the cabins of cars these days just because the engines are so quiet. And it's not just EV makers that are doing it.
