Ported VQ35HR lower intake manifolds, hand ported and finished in 80 grit followed by a light cross buff and ceramic coated to help with IAT temps Excellent bolt on mod for VQ'S looking to get more pep out of their cars This manifold fits all models with the VQ35HR engine, including the '07+ 350Z & '07+ G35 Sedan. This upgrade is fairly simple but requires the removal of the upper plenum and fuel rail/injectors. Installation time may take up to 2 hours.
