The Skunk2 High Velocity Universal Intake Kit (343-99-0605) is engineered to maximize air mass delivery and reduce intake temperatures for custom induction systems. At the core is a massive 6.8-inch diameter high-flow air filter featuring a double-cone design. The inverted inner cone expands the surface area to over 317 square inches while guiding airflow to minimize internal turbulence.

This kit features a composite velocity stack with a dimpled surface, utilizing aerodynamic principles similar to a golf ball. These dimples create an energized boundary layer that prevents air separation and reduces surface drag as air enters the bell mouth, resulting in higher intake velocities. Flow testing and CFD analysis confirm this configuration delivers 20% more air-mass than standard filter designs.
