DId you find a source?

Interesting, I was checking my engine today and notice that one of my ducts has a slit in it ...

didn't find an official source... they seem to be plentiful on eBay, but I don't love buying from unknown buyers.

Thumbs up replaced mine

Thanks for the helpful hints guys.

I took GuestFromTampa’s advice and I purchased one of these https://www.spectreperformance.com/8...-duct-hose-kit (from Amazon though)

It looks like belarus27 and Davery went the same route.

I really like the set rediesel posted, but if I had an extra $4K, it would probably go into bigger turbos and a tune

There’s more than enough duct hose for two inlets, but you need the couplers to mate the duct hose to the MB adapters. I emailed the company to see if I can purchase the couplers separately so I can do the other side, otherwise I’ll order another kit.

You can see that the original duct is torn up (not sure why it’s just the right side; left side is fine)

The OEM duct is glued into the MB adapters, so you’ll need to pry/pull/cut it off. The couplers in the spectre kit will fit into both adapters well. I didn’t glue them in, but you could do that. I just pressed them into place.

I cut the supplied duct hose in half, since there’s much more than enough. I don’t know if my OCD will let me leave this as is (two little funky bends in the hose). I may cut the duct in half again.

Anyway, for anyone else needing a solution, this seems to work fine
