GReddy Intake Plenums are designed to maximize performance in highly tuned engines. The fine cast-aluminum intake manifolds allow for large volumes of air to get evenly distributed to the cylinders. To achieve the most form larger turbochargers at higher boost levels, a smooth flowing GReddy Intake manifold is a must.

The throttle mounting position has been reviewed by flow simulation analysis to distribute between each cylinder equally. Also both the inertia supercharging efficiency and the maximum power were considered. So the tank capacity has designed as bigger 82% than genuine one.
The suction efficiency at the middle range revolution and the response have improved by funnel shape of the intake port. Due to the port diameter extended Dia 58 from Dia 56, the increased air volume at the high revolution can inhaled from the tank effectively.
