I have a used but in very good shape K&N Typhoon intake for a 370z and G37. Used for about 5000 miles. The intake comes with everything except the 2 small mounting brackets and breather setups (which can be purchased from K&N).
When I bought the intake, it was missing a filter (got lost with the other pieces) so I did pick up a brand new K&N filter so one filter is used with only about 5000 miles and the other filter is brand new. Note - this is
not CA CARB legal.
Don't need this so selling for a very reasonable price of $225 shipped anywhere in the lower 48 states.
