Raw air line: where to find used?

I'm looking for a used raw air line for my 2021 GLS 450. The left clip where it connects to the airbox has snapped off. I've looked and I can only find them as a whole assembly new for $310-450 which is absurd. I only need the swivel end piece but it can't be bought separately. Does anyone have good source for used parts?

Here's the part I need:


I found a used version on eBay for $200. It's a different model with the same airbox connector:



Any thoughts on buying this and swapping the connector as an alternative to buying a new assembly?

This would be a good use of 3d printing. Can you see if someone local can scan and print the part you need?

Hard to see what part snapped off... What about those videos on Utube using cotton or baking soda and superglue to fix plastic parts. Worth a try before spending hundreds.

Not a bad idea. I'll see if I can find the tab on top of the manifold. It fell off when I removed the hose to replace the air filter.

So ive done this before with varying success. It best done on parts that dont have to be moved of flexed to snap into place. It's very inflexible. It can work but when someone else winds up touching it, they will inevitably break it. JB Weld plastic weld is a great glue. Prep is everything, and you can/should still use a crutch or support.

I don't think adhesives or 3D plastics would survive well in the engine compartment. If I was going to attempt a repair, I would fabricate a replacement clip from some metal (sheet or bar stock) and attach it with screws. Won't be pretty, but it would be functional and permanent. But if the existing part has become brittle from age and heat, you night need to buy the new assembly.

One of the locking tabs is broken off, only noticed it when I replaced the air filter. I agree with you, just the price for a new hose assembly when I only need the end is absurd.
