Ok I bought these. I finally got sick and tired of replacing the buffers after they broke. They never seem to last more than a year. And my engine is pretty smooth too. It wastes so much time changing these things and when the knocking starts under the hood it’s stressful because I don’t know what it is till I get the car home.
So here they are. 4403K84 from McMaster Carr. $38 shipped to my door. Ouch…much more expensive than the Febi, URO, CRP or MTC which don’t last at all. Less expensive than the Mercedes
OEM at $24 each.
Time to try these out. I’ll report back when they break. They appear to be a very nice silicone rubber. At $13 each I hope they last. Even at 3x the price of the shoddy ones they’ll be worth it if they last 3x as long. Because it wastes time to replace them.

At McMaster Carr I found some "Extreme-Temperature Vibration-Damping Sandwich Mounts with Stud, Orange, M6 x 1mm Thread, 90 lbs. Capacity".

Year and a half no problem, just make sure the air cleaner drops cleanly onto the studs.
URO, please take note and strive for this American quality.
