Skunk2 Honda D-Series VTEC Applications - Ultra Race Intake Manifold - D VTEC

The Skunk2 Ultra Race Intake Manifold engineered for D Series Vtech engines is cast as a two-piece manifold from aircraft grade A356 aluminum, and features provisions to mount secondary injectors underneath. The modular design means the plenum volume can easily be increased using simple spacers, and the runners can be freely ported for additional flow and volume. The versatility of this manifold allows enthusiasts and engine builders to tune the manifold combination to best suit their needs.

Recommended for high-performance naturally aspirated engines up to 450hp, and turbo/supercharged engines from 650hp and up.

Each manifold is vacuum tested, black wrinkle powder coated and finished-off with our Signature Skunk2 Pro-Series nameplate.
