What is the difference between this and the 12 or 18-injector AMS Nissan GT-R intake manifold?

This is the standard configuration — a single fuel rail supporting 6 injectors per bank with no auxiliary rail. The 12-injector version adds an aux fuel rail for additional fuelling capacity, and the 18-injector version adds a third rail for extreme power builds over 2,000 horsepower. The manifold construction, plenum design, and performance characteristics are identical across all three versions.

How does the AMS Nissan GT-R intake manifold improve power across the entire power band?

The AMS Nissan GT-R intake manifold uses two meticulously molded and tapered carbon fiber plenums to minimise turbulence and maintain maximum airflow velocity and pressure from the moment the turbos spool through to redline — delivering consistent gains across the full RPM range rather than only at the top end as many competing manifolds do.

Can I upgrade the AMS Nissan GT-R intake manifold to a 12 or 18-injector setup later?

Yes. The manifold includes provisions for additional fuel rails, allowing a future upgrade to the 12 or 18-injector configuration as power targets increase without replacing the manifold itself.

Which fuel rails are compatible with the AMS Nissan GT-R intake manifold?

AMS/Alpha fuel rails are the only guaranteed-compatible option. Stock factory fuel rails are not compatible. Other third-party fuel rail kits may work but cannot be guaranteed by AMS.

What testing has the AMS Nissan GT-R intake manifold undergone?

The AMS Nissan GT-R intake manifold has undergone 144,000 pressure cycles from 0-50psi in a high-temperature environment simulating over 20 years of typical GT-R use, followed by a burst test at over 150psi. No other Nissan GT-R intake manifold on the market has been subjected to an equivalent testing regime.

Description

AMS Performance Alpha Carbon Fiber and Clear Billet Intake Manifold with Standard Fuel Rail (6 Injectors) for R35 Nissan GT-R

Nissan GT-R intake manifold from AMS Performance is the Alpha Carbon Fiber Billet unit in clear anodized finish with the standard 6-injector single fuel rail configuration, a fully CNC-machined billet aluminum manifold with hand-laid carbon fiber plenums for the R35 Nissan GT-R (CBA-R35, DBA-R35, EBA-R35, VR38DETT 3.8L V6 twin-turbo, 2008-2025). This is the entry-level Alpha manifold for builds not yet requiring the additional fuel rail capacity of the 12- or 18-injector versions, while delivering the same broadband power gains, the same aerospace-grade carbon fiber plenum construction, and the same dowel pin-aligned runner precision as the higher-specification variants. The AMS Nissan GT-R intake manifold is over 30% lighter than the leading cast aluminum alternative and delivers higher horsepower and torque from the moment the turbos begin to spool, consistently throughout the entire RPM range without compromising throttle response or power delivery.

Why the AMS Nissan GT-R Intake Manifold?

The AMS Nissan GT-R intake manifold uses two meticulously molded and tapered carbon fiber plenums, one per cylinder bank, to channel charged air efficiently to the CNC-machined aluminum velocity stacks leading into the runners. This minimizes turbulence and maintains maximum airflow velocity and pressure across all operating conditions, producing power gains throughout the entire band rather than only at the top end as many competing aftermarket manifolds do. Dowel locating pins align the upper and lower runner sections with tight tolerances, eliminating the steps and protrusions at the upper-to-lower joint that introduce turbulence in competing designs. Dual MAP sensor ports allow bank-to-bank boost pressure monitoring, with extra vacuum ports on the plenums for ancillary systems. The manifold retains PCV function and operates exactly as the stock unit for everyday drivability. The manifold is also provision-ready for a future upgrade to an additional fuel rail if higher power targets require additional fuelling capacity beyond the standard 6-injector setup.

Nissan GT-R Intake Manifold: Construction and Testing

The carbon fiber plenums of the AMS Nissan GT-R intake manifold are hand-laid using aircraft-grade epoxies and carbon fiber layering techniques engineered to meet the strength tolerances of critical aerospace components. The finalized design underwent 144,000 pressure cycles from 0-50psi in a high-temperature environment simulating over 20 years of typical GT-R use, followed by a burst test at over 150psi a testing regime no competing Nissan GT-R intake manifold has undergone. The billet aluminum runner sections are CNC-machined and finished in clear anodize. As hand-laid motorsport-grade carbon fiber parts, slight imperfections or weave pattern variances are a natural characteristic of the construction method and are to be expected.

Additional Information

The Bulletproof Automotive website contains many thousands of products purchased in multiple different currencies. All of the prices are entered manually and accurately at the time of entry. Due to the consistently fluctuating international exchange rates, at times prices may not be able to be honored at their original intended rate. We apologize for any inconvenience this may cause, unfortunately our website is unable to compensate dynamically for what can at times be volatile changes in the cost of items due to currency values fluctuating, changes in prices from suppliers, changes in shipping and import duties, and other factors. Rest assured that any order you place on line will be at zero risk to you in this area. If in the event your order cannot be fulfilled at the original intended website price we will offer you a 100% refund, no questions asked. We will continue to do our best to maintain updated prices and we will always continue to offer our price match guarantees as well to ensure our prices are always the best for you. In short, prices may change without notice. It is always advised to give us a call prior to placing your order online to confirm availability and to confirm current pricing.

Shipping Policy

Items that are in stock in the US, either at Bulletproof’s warehouse or at a supplier’s warehouse, are generally delivered within 7-10 days. Special order items from overseas take considerably longer. As a courtesy Bulletproof offers delivery estimates to our customers which take into consideration manufacturer availability and shipping schedule. These estimates represent our best guess based on previous orders from the manufacturer and do not in any way imply a guaranteed delivery window. Many manufacturers work in a “just in time” inventory system and often take 2-20+ weeks to produce an item once an order is submitted. All deliverable items are then sent to our Japanese warehouse. Bulletproof ships a minimum of one full ocean freight container every month from Japan, oftentimes more than one a month. Ocean freight takes an average of 4 weeks. Typically it breaks down to one week in Japan for paperwork and customs, two weeks by boat and one week in US customs/clearance. Due to the wide number of variables between manufacturer and shipping schedules, delivery estimates are simply just that – estimates. We attempt to estimate conservatively and we usually deliver faster than our estimates suggest. It is not Bulletproof’s policy to guarantee delivery time of any special order item, this is impossible for us to do. By ordering you acknowledge that there is no required delivery ETA and an order may not be canceled or altered due to manufacturing or shipping delays, all ETA’s are provided as a best guess only. Please review the full Terms & Conditions here.

BP Pricing Difference

We do pricing a little differently on our JDM brands and we believe in making things simple and clear. No hidden fees or surcharges. Every price you see includes the shipping cost to our office in Los Angeles, California and all the associated taxes/duties/fees for bringing the products into the US. The only shipping you ever pay is from our facility in the US to your location. Be wary of resellers that don’t include the cost of international shipping in their pricing on JDM parts. While we believe we’ll always have the lowest all-in price on JDM products, we offer a price match guarantee for all authentic parts purchased from authorized dealers as well. For many international customers, it’s much more affordable to ship from the USA than from Japan directly, as the air freight and ocean freight costs are typically much less. However, for customers looking to ship directly from Japan outside of North America, or domestically in Japan, we can provide pricing specifically for that scenario. Please do not hesitate to contact us with any pricing questions or concerns. Please email us at sales@bulletproofautomotive.com with any inquiries.
