There is a part number stamped on it, get this and then search online to see what it is worth. VW/Audi part numbers are grouped similar to ....'058 133 678' and may have prefixes or suffixes. Basically the part number is 'model' 'section' 'number' not that matters. Make sure to check the PCV system under the intake going into the block forward. These dry out over time from oil vapors and the plastic can fall apart and the valves gum up. The check valves are one way valves which stop intake leaks so test them and make sure they are working properly. If you remove one make sure to put it back in the proper orientation or you will have an intake leak.

$34 jesus!! try germanautoparts.com same check valve but without the T. you can get a regular check valve and get a t fitting from the local autoparts store for a lot less.
I would hate to see what the shipping would be on that 34 dollar part.

Is there any downside to these, considering they are 1/40 the price? It says they work from 2 to 29 in. Hg, and up to 150 psi. I don't see how that's a problem there, but is there anything else i'm looking past?

Operating temperature... I don't see data listed for that.

The plastics themselves have a melting point around 330f and they are considered safe to around 240f. I have about 6 of them in my engine bay and look/work fine after 4 months.
