The Skunk2 Ultra Series Street intake manifold for L15B engines is a modular, two-piece cast-aluminum design developed to reduce restriction and improve airflow for stronger torque and power. The removable plenum allows for volume changes and porting, while long 8.72" runners and flow-tested velocity stacks promote even cylinder distribution. Each manifold is CNC-machined from high-grade 356 aluminum and inspected for quality.
