The Skunk2 Ultra Series Intake Manifold with Black B VTEC is designed to enhance performance on Honda B16A, B17A, and B18C engines. Built with a three-piece modular design, this intake manifold allows for easy disassembly, porting, and plenum volume adjustments through removable components. The innovative CFD-optimized design reduces restrictions, delivering significant torque and horsepower gains over many competitors. Featuring a 3.5L plenum volume, 90mm throttle body inlet, and a 5.0 Ford bolt pattern, it provides a versatile upgrade for high-performance applications. The manifold's black powder-coated finish adds durability and a sleek appearance, making it suitable for racing or enthusiast builds. The raised 87mm velocity stacks and generously cast runner walls facilitate maximum airflow and porting potential, supporting optimal power production across a broad RPM range. Provisions for additional injectors on the bottom side of the runners offer further customization for tuning needs. Compatible with all B series VTEC heads, this manifold includes high-grade mounting hardware and a thermal flange gasket to ensure secure installation. Optional billet aluminum plenum spacers in 1L or 2L sizes can be added to customize plenum volume and tuning characteristics. With its advanced design, this intake manifold is ideal for those seeking increased performance and flexibility in their Honda or Acura engine builds. Note that this product is not CARB approved and requires acknowledgment of CARB regulations for legal use in emissions-controlled environments. Designed for racing and off-road use, it provides a robust upgrade for performance enthusiasts aiming for maximum airflow and power gains.
