Question on 2 different Combo Catch Cans
 

Can someone possibly tell me the difference between these 2? One has the breathers and the other has the option of pressurized/Non-pressurized. Im up in the air on which one to get.....

2016 Nismo 7AT
Thnx in advanced...

You can have a perfectly functional set of cans for 100 bucks total from Amazon. If you're interested in going that route PM me and I'll give you details.

Sounds like you have some research ahead of you.
The ones with filters are for deleting your PCV system and venting the crankcase to atmosphere. My best guess on the pressurized/non-pressurized is one is whether or they can handle boost. (edit: Rusty has this correct below)

I'm with Betty though, I bought some inexpensive ones and they seem to work fine.

The pressurize/non-pressurize is for the radiator catch tank. The Z uses 2 different cooling systems. The older system. The pressurized cap is on the radiator. The newer system. The pressurized cap in on the reservoir. Forget which year they changed.

:iagree: I just bought one from SOHO and had to specify pressurized or non pressurized for radiator reservoir side.

2012 is when Nissan made the coolant reservoir pressurized.
