Details:

The Skunk2 Ultra-Race Series Intake Manifold for Honda K20A/K20A2/K20Z1/K24A1 Engines is the preferred manifold for high horsepower street and race engines. All Ultra manifolds feature tapered runners with trumpet profiled entries and plenums that have been designed and optimized using CFD and on the dyno. The short tapered high volume runners combined with an oversized plenum runners favors maximum top end power over lower end power and response.

The Skunk2 Ultra Race Manifold 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 and finished-off with our Signature Skunk2 Pro-Series nameplate.
