The Alpha Performance R35 GT-R Cast Aluminum Intake Manifold Plenums have been painstakingly designed by AMS to be the most efficient and power producing cast intake manifold available. Attention to every detail was accounted for when creating this high performance induction component. If you’re familiar with the Alpha product line, you already understand that our aspiration has always been to offer you much more!
Like our Carbon Fiber Plenums and unlike most aftermarket GTR Intake Manifolds where gains are seen near the top of the power band and suffer near the bottom, the Alpha GT-R Cast Aluminum Intake Manifold Plenums provide global performance. Compared to the leading cast aluminum GTR 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 GTR intake manifold starts making more power and torque. The best part is nothing is sacrificed in terms of response or power under the curve.
Based off of our Championship winning Carbon Fiber Intake 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 cast aluminum 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!
Please Note: Alpha upper intercooler pipe adapter for current Alpha intercooler piping or full Alpha Induction Kit is required. While other fuel rail kits may work (stock rails are not compatible), AMS can only guarantee AMS/ALPHA Fuel rails to be compatible with this Intake Manifold.
