AMS Alpha Cast Plenum Intake Manifold, Triple Rail | Nissan GT-R R35

This is the AMS Performance R35 GT-R Intake Manifold with Cast Aluminum Plenums in its triple fuel rail configuration for 18 injectors, built for VR38 engines aiming past 2,000 hp. The extra rail places injectors at an optimized spray angle for better atomization.

The manifold follows the design of the Alpha carbon manifold: a molded, tapered cast plenum per bank, CNC billet velocity stacks, and billet upper and lower runners aligned with dowel pins so there are no steps in the airflow. AMS says it makes more power and torque across the band than the leading cast GT-R manifold.

AMS cycle tested the design from 0-50 psi in high heat to replicate 20 years of driving and burst tested it past 150 psi. Dual MAP ports allow bank-to-bank boost monitoring. This listing is the clear anodized finish.

FAQ

Can I use my stock fuel rails?
No. Stock rails are not compatible. AMS can only guarantee its own fuel rails with this manifold.

Can I use my stock throttle bodies?
Yes. Adapters for the stock throttle bodies are included. Alpha big bore throttle bodies are sold separately.

What about the PCV system?
AMS notes custom PCV routing is needed if you want to keep that function.
