PRICE DROP! Alpha GT-R Carbon Fiber Intake Manifold

The Alpha Performance R35 GT-R Carbon Fiber Intake Manifold is back in stock now with a PRICE REDUCTION! Optional parts kits are also now available. The Alpha GT-R Carbon Fiber Intake Manifold has been painstakingly designed by AMS to be the most efficient and power producing one available. 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.

Third Fuel Rail Engineered To Support Incredible Power

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.

Larger, Perfectly Molded Carbon Fiber Plenums

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!

The Difference Is In The Details

Each manifold is matched to its upper and lower running section to maintain the perfect flow of air from the throttle body to the cylinder heads. To achieve this, our engineers called for very tight tolerances where the upper and lower sections adjoin. That wasn’t enough though. To perfectly align the upper and lower ports, they took it a step further and installed dowel locating pins to ensure there were no steps or protrusions that could cause unnecessary turbulence found on other aftermarket manifolds.

Unimaginable Strength

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!

Choose an Anodized Color Finish

Would you like your Alpha intake manifold to complement the color of your GT-R? For an additional fee you can choose from a stunning array of anodized finishes to give your engine bay that added custom touch!
