I am preemptively replacing my air dryer cartridge due to contamination worries.

Which Air dryer is this and which cartridge do I need to order?

Looks like a Wabco with a twist on.

Thanks!

I have the same air dryer. I bought mine off amazon. here is the part numbers .
wabco r950011   i bought the torque brand , works perfect.   Just make sure when you remove it you pump all the air pressure down on the air tanks or it will scare the sh-- out of you when it pops. you should also invest in the wrench to take it off.  you needs a filter wrench that is 5 1/4-5 3/4"

MANY thanks for the speedy reply. I ordered the two pack

I've had that scare a few times... Good thing I'm heart healthy!
