plastic inner wheel arch liner that goes around the ABS pump 92850422111, should have foam seals in the grooves, which usually falls apart when its removed.
can still be bought new, but if anybody in the future wants to get some aftermarket foam its dimensions are 20mm wide and 35mm high.
just measured a genuine new one.
should have measured them before i fit them for their total length, but approx 75"should easily be long enough
cheers

From time-to-time I look for suitable closed-cell foam with those dimensions that can purchased in bulk. So far, I haven't found it.

Last time I ordered replacements for a client the price from Porsche was so-almost-close-to-reasonable that I didn't expend energy to look hard for bulk material.

I used this stuff to replace the falling apart foam on my '89 many years ago..

From memory I used the 9mm wall, 13mm ID which squished into the slot. Its closed-cell, ntrile rubber, foam pipe insulation - our local hardware store has it for about $4 per 2m.
