ALPHA GT-R Cast Plenum /

The Alpha Performance R35 GT-R Cast Aluminum Intake Manifold Plenums are designed by AMS for efficiency and power, increasing HP and torque across the entire power band. The larger, tapered cast aluminum plenums effectively channel charged air, reducing turbulence. Each manifold is matched with billet upper and lower runner sections with tight tolerances and dowel locating pins for smooth, continuous flow. Rigorously tested, including cycle testing from 0-50psi and burst testing exceeding 150psi. Supports over 2000+ horsepower with an optional third fuel rail. Optional Alpha Billet Big Bore Throttle Bodies are available for cars over 800HP. Custom anodized color finishes are also available.
