• One of the biggest issues with the Greddy intake manifold kit or others like it is that the IACV flange is suited for the Series 1 or 2 RB25DET.  If you have a R34 or WNC34 with a RB25DET NEO Engine then you have a completely different Idle Air Control Valve (IACV) & if you wanted to use these forward facing plenums you would heave to buy the old series 1 or 2 one & re-wire that in.
  • Greddy Intake Manifold Plenum is a must have for people looking for ways to increase air flow into their engine. This manifold will improve mid to high RPM range power.
  • Get rid of the factory cross over type intake manifold with the Greddy high flow intake manifold. Greddy manifold allows bolt on of Q45 large throttle body for higher performance use!
