The latest in Skunk2 Racing's line of Ultra Street Manifolds has arrived for the 2016—2020 Honda Civic L15B! The Ultra Series Manifold ensures optimal intake performance for maximum horsepower gain versus traditional single-piece intake manifolds. Skunk2 Racing's modular cast aluminum intake manifold can be easily disassembled for ease of porting, cleaning, and plenum volume changes via the use of the company's separately sold spacers. The expandable plenum gives the ability to perfectly curate intake airflow and volume for to maximize application potential.
Skunk2 Racing Ultra Series Manifolds are the result of decades of research and development. The manifolds are engineered using the latest in Computational Fluid Dynamics software, and countless hours of dyno and real-world testing on race cars and streetcars alike. Optimized plenum design evenly distributes airflow to all cylinders under dynamic load conditions. The Ultra Series Manifold is cast from high-grade 356 aluminum alloy due to its high strength, low weight properties and CNC machined for precision fitment. Thick-walled intake runners leave large allowances for porting to minimize chances of breakthrough and a larger 70mm throttle body opening offer maximum airflow.
