Skunk2 Ultra Series Race Intake Manifold – Silver – Honda / Acura K Series 3.5L


Skunk2 Ultra Series Race Intake Manifold – Silver – Honda / Acura K Series 3.5L


As a result of years of research and development, this multi-piece cast aluminum design offers numerous advantages only allowed by a modular design.

Continuing the legacy of the Pro-Series intake manifold, including the use of the latest in CFD (Computational Fluid Dynamics) software, engineers have created a 3-piece modular design that allows for easy disassembly, porting, and volume changes in the plenum (4.5L and 5.5L) through the use of optional plenum spacers. Extensive in-house dyno and on-car testing has shown a huge increase in both horsepower and torque gains over other manifolds.

The new Ultra-Series intake manifold comes standard in 3.5L trim, is made from a high-grade 356 aluminum for increased strength without sacrificing weight, CNC-machined for a precise fit, and individually inspected for quality assurance.

The large 90mm throttle body opening, 87mm velocity stacks, and hi-velocity intake runners with smooth transitions allow the Ultra-Series intake manifold to be used with built, high- horsepower, naturally aspirated or forced induction setups. The new Ultra-Series intake manifold offers cutting edge intake technology at an affordable price.
