The original Alpha Performance R35 GT-R Carbon Fiber Intake Manifold was painstakingly designed by AMS to be the most efficient and power producing manifold available. Now, AMS has now made it possible to run 18 Injector Dynamics injectors (not included) in the same award winning design! Attention to every detail was accounted for when creating this high performance induction component. On looks alone, you might agree, it makes the perfect centerpiece for your GT-R’s engine bay. However, if you’re familiar with the Alpha product line, you already understand that our aspiration has always been to offer you much more!

Unlike most aftermarket manifolds where gains are seen near the top of the power band and suffer near the bottom, the Alpha GT-R Carbon Fiber manifold provides global performance. Compared to the leading cast aluminum intake manifold on the market, our piece not only produced more HP and torque but it did so through the ENTIRE POWER BAND! From the moment your turbos spool up, the Alpha intake manifold starts making more power and torque. The best part is nothing is sacrificed in terms of response or power under the curve.

Sample Alpha 10 GT-R Test Results: Alpha Performance GT-R Carbon Fiber Intake Manifold vs Stock (22psi)

Proper function of the plenum is extremely important to the performance of any intake manifold. In the case of the GT-R, there are two plenums one for each bank. Not only should they be sized for correct volume, they provide even more benefits when shaped in such a way that distributes charged air more evenly amongst each of the precisely machined CNC aluminum velocity stacks leading into the runners. Both lightweight carbon fiber plenums are molded and tapered to channel charged air effectively reducing turbulence and accelerating the delivery of charged air to the engine. By maintaining balance and sustaining maximum airflow velocity and pressure when needed, your GT-R benefits by outputting more horsepower

Optimally designed CNC billet aluminum velocity stacks.

We wanted to offer an intake manifold with the highest level of strength and reliability so we teamed up with an expert in the field. Using aircraft grade epoxies and carbon fiber layering methods, we constructed a manifold that would match the strength tolerances of key components used in the aerospace industry. We then cycle tested our finalized design 144,000 times from 0 50psi in a high heat environment in order to replicate over 20 years of operation by the average GT-R owner! In the end, a burst test was performed where the test manifold was subjected to over 150psi! No other manifold on the market has undergone such grueling tests!

For extremely high-powered GT-Rs, provisions are available on the manifold and an additional Alpha fuel rail can be installed which will supply enough fuel to feed a VR engine capable of producing over 2000+ horsepower. Positioning of fuel injectors is critical since optimizing the spray angle of the injector can improve fuel atomization and efficiency. Our engineers took all of these ideas to heart when designing our third rail setup. This option is available for customers wishing to change their standard two rail Alpha carbon manifold to a three rail system down the road.

Outgrown the stock GT-R throttle bodies? If your car is making over 800HP, they are probably a restriction. We manufacture the largest throttle bodies for the R35 GT-R designed to work with this intake manifold.
Features:

• Same Championship Winning Design as our 12 Injector Version
• Capable of utilizing 18 Injectors (not included)
• The most powerful VR38 intake manifold on the market
• Show stopping design
• Over 30% lighter than the leading cast intake manifold
• Dowel pin aligned for smooth, continuous flow between upper and lower runners
• Dual MAP sensor ports allow for monitoring bank to bank differences in boost pressure
• Does not retain PCV functionality but custom set-ups are possible
• Extra vacuum ports on plenums
• Upgrading from a 12 injector to an 18 injector center section is an option

Fitment:

• Nissan R35 GT-R 2008-2020

Note:

• 18 Injector Upgrade From Std 6 Or 12 Injector Manifold. Upper Section Only
• Custom PCV routing would be needed if the owner wishes to retain its functionality
• Alpha upper intercooler pipe adapter for current Alpha intercooler piping or full Alpha Induction Kit is required.
• Injectors, injector wiring, and fuel lines are not included and must be custom designed and built.
• While other fuel rail kits may work (stock rails are not compatible), AMS can only guarantee AMS Fuel Rails to be compatible with this intake manifold.
• Custom color anodizing can add 2-4 weeks to build time.
