Used OEM Z32 Lower Intake Manifold for all Nissan '90+ 300zx models. Located below the upper plenum, the Lower Intake manifold connects and redirects the fresh air entering the engine into the cylinder heads. The lower intake plenum can be damaged when removing the upper idler stud or if dropped.
If you are swapping an cylinder head styles (OLD STYLE <> NEW STYLE), you will need the appropriate Lower Intake Plenum to ensure that the ports match correctly.
Please specify the appropriate injector type when ordering from the options menu below:
Please note: Lower intake plenums ARE NOT interchangeable between new style and old style cylinder heads. If you are attempting to install new style injectors into an old style lower engine, Z1 Motorsports highly recommends the usage of our Z1 Motorsports Injector Adapter Kit to ensure a proper installation and vehicle performance. Installation of a NEW STYLE Lower Intake manifold onto a 30P or 40P style cylinder head will result in incorrecting matching of intake ports.
