New Cusco product
 

Come across this new part released by Cusco, don't really know what it does and cant understand why its so expensive.

Looks to me that it is some sort of check value, does anyone know how you would benefit from this part.

Hmm, not sure about that but i saw they have a new air/oil seperator too i'm waiting on them to come in but looks better than the street catch can they have now.

Without being able to read Japanese, I will hazard a guess and say it looks like a check valve on the breather system for boosted applications. Just a guess though.

It looks like some sort of one way valve for the block breather.

Edit: On further reading its like a second PCV valve aimed at creating a vacuum in the block which is good for a whole heap of reasons.

anyone figured out what this is good for?

is it worth $580 to put a vacuum on the block....
