Air duct muffler in rocker panel

Post by Max911 »

Dear everybody, I'm finally with old rocker panel removed.
Now I need to renew the old card air duct muffler...they seems good but my heat exchanger have been repaired with fibreglass ...full of oil and I don't want the car to smell of old oil

Could you please tell me were I can buy the card tube to replace them? I mean I want to rebuild them...new item from Porsche 911.572.025.02 cost 165€!!!! And with maximum respect to Porsche I don't intend to spend 330€ for 2 card tubes...

By my local spare parts warehouse they have no generic tubes with diameter above 60mm...I need 95mm diameter and 700mm lenght

Thanks for your help!

Zero answers at all..probably my poor english is far from getting better... :(

or probably you didn't had my problem and could refit your air muffler...

by the way I briefly resume my solution... it could be useful for anyone in my situation or to get further suggestion from you

my air muffler contained in rocker panel was in bad condition, with holes and a bad bad oil smell: moreover the insulating material inside due to age and warm was deteriorated and going into dust...and when you use warm air in the car or defrosting windscreen this bad dust would come out and I would breathe it!!! :?

I finally found a similar tube, I used end cap and internal net, I fitted new insulating material but closed between two aluminium sheet in order not to get any part of it or dust into the cabin.

Total cost: 13€ for the 2 tubes, 40€ for insulating material (actually an enormous industrial 3square meters...no smaller available :? ) 24€ for high temperature glue for end cap (absolutely overhestimated...), total 77€

Normally I search for OEM spare parts or similar quality...but in this case to buy original new part that can affect health of people inside the cabin... (breathing dust of insulating material :shock: )
Probably 50 years ago nobody cared about this issue... well hidden inside rocker panels

Thanks for your reading
