Does it say made in Germany?

I'm not sure if you're asking me or the original poster. But I replaced my original air compressor w/ one from Ebay 1.5yrs back and now am in need for another one so I thought to see in getting a OEM new one.

The Thomas J

see how it says made in Germany? That's an OEM.
Arnott sells two AMK units. The cheaper One is made in China, the other in Germany.

Ahhh I see! Thanks for the pic reference I was unaware there were two like such. The one I've received was from ebay and most likely made in China. It didn't have a manufacture on it nor the date stamp/sticker. It was ~$150 but I rather pay slightly more to avoid a cheaper one that'll break down. The one from OEM are $400+..... do you know of where I can get a cheaper with part number: 164320120480

That's what you are going to pay for a German AMK unfortunately. I paid $403 in August for mine. Currently $427 at RockAuto. I bought the Bilstein, which is the German AMK.

I just paid $427 for mine with tax and shipping.
​​​​it's worth the extra money if it lasts as long as the OEM

Am I correct in assuming the AMK P-3722 from Arnott is the best one they sell???
I’m planning to install a new P-3722 compressor today or tomorrow and can’t decide whether to replace the valve block or not.
My only issue is MALFUNCTION has gone from intermittent to constant on my dash…no sagging no matter how long I let it sit and ride height is good.

To my knowledge, there is only one AMK compressor. Arnott labels it as P-3722.

I would not bother changing the valve block until you have a known failure. They seem to fail as a result of excessive pump running due to leaky springs, particularly in a humid environment. From the sounds of it you have simply exhausted the pump's life.

I replaced both compressor and valve block (manifold). bought them as a kit (arnott brand) from FCP euro for about $650
Replacement is not hard by removing passenger side wheel well liner.
If you could remove the front bumper as well, it will be a much easier job.
might be good idea to replace the intake air pipe to the compressor and the air filter on it.
