Skunk2 Universal High-Velocity Intake Kit – 3.5" Coupler

The Skunk2 Universal High-Velocity Intake Kit with 3.5” Coupler is designed to reduce heat soak and maximize airflow and velocity across virtually any induction system. Engineered using advanced fluid dynamics and airflow modeling, this system ensures higher intake efficiency and improved engine performance for a wide range of custom and universal applications. At the heart of the kit is a massive 6.8” diameter high-flow, low-restriction air filter with a unique double-cone design. The inverted inner cone expands filter surface area and promotes smoother, faster airflow by reducing turbulence inside the intake path. Skunk2’s composite velocity stack takes performance a step further with an innovative dimpled surface, similar to a golf ball. This design forms an energized boundary layer that minimizes drag and keeps air attached as it curves into the bell mouth — increasing air mass and flow stability. CFD testing shows this design flows up to 20% more air mass than conventional intake filters, resulting in more efficient combustion and measurable horsepower gains. Perfect for custom builds, turbo or naturally aspirated setups, and universal intake projects, this kit offers race-proven performance with easy installation.
