370z Z1 Motorsports Ported Lower Intake Manifold

This is achieved by opening the runners to their largest possible diameter while maintaining their shape for maximum flow. 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.

While the Z1 Ported Lower Intake Manifold works very well alone, Z1 recommends the use of our Intake Plenum Power Mod for increased efficiency and power. This can be done at the same time for moderate power gains on Naturally Aspirated and Forced Induction engines.
