GReddy 09+ Nissan GTR RX Intake Manifold Plenum w/ Inj Boss

The fine cast-aluminum intake manifolds allow for large volumes of air to get evenly distributed to the cylinders. To achieve the most from larger turbochargers at higher boost levels, a smooth flowing GReddy Intake manifold is a must.

Car Make: Nissan

Type: GTR

Car Year: 2009-on

(R35) VR38DETT

Cast Aluminum high-flow intake Manifold for VR engine with additional Injector Bosses
UPDATE: (now pre-drilled, with include billet plugs)

For extra high horsepower applications. This RX SPL manifold features 6 boss locations to allow for 6 additional injectors to be positioned at the base of each runner for secondary injectors.

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.

Larger volume , for high horsepower applications.

3 pices, larger runners (58mm), 2x large volume end tanks (+85%)

※ Requires 1/8 PT Screw machining on the stock balance tube for installing a blowby union.

* factory thorttle body compatiable. or ** RX Billet Throttle Kit.
