Hi - I recently installed my Z1 ported plenum. I ended up sending them a different core and have my original available.
It is off a 2013 Z with under 4k on the clock.
I have cleaned it up and it will come with the lower gasket (I had a spare) but not the ones for the throttle bodies, bolts are also included.
SOLD
Perfect if you are going back to stock, or want to do what I did and send a spare core to Z1 first without having to take your original off.
(To recap -
This core is completely unmodified - other than being really, really clean. ha ha)
PM me if you are interested or have any questions. Thanks!
