2023 Nissan Z Valve Cover Breather

Hello,

Has anyone tried this crankcase breather filter that goes on your valve cover?

It's supposed to release unwanted crankcase pressure.

great way to get Oil stains in your engine bay.

the orginal breather "should" vent back into the intake so anything is burnt off so it is already venting but stock cannot drip down.

if you want to upgrade then a catch can is a better idea

not needed unless you are making big power.

I swear by them on BMW engines where catch cans actually to not work (stupid tricky German engineers)

Same engine as before, what do the red sport guys do?

I saw many people running them on the Supras too
