I'm not sure if they upgraded them
Over the years... but from what
I read there is a difference in oem
Base to sport model / Nismo ones.
But anyhow, these are New removed from
My 16' Nismo from day one.
So they worked very smoothly and
Opened as they should.
I switched all my hinges and
Added Z1 hood struts to match my
Hatch struts was only reason these
Were removed was I wanted match
To The Z1 hood struts.
I found the ones from Z1 much more difficult to
Open than oem personally.
But then again Z1 did state that.
Hope that helps and lmk if
U need them.
