CAC Hose 4in I.D. x 7in long - Black

The CAC Hose 4in I.D. x 7in long in black from Vibrant Performance is a premium silicone intercooler hose engineered for turbo and supercharged engine builds. Whether you're upgrading a stock forced-induction system or fabricating a custom high-performance engine bay, this straight-section hose delivers the durability and thermal stability required for sustained boost pressure and extreme underhood temperatures. Designed for builders who demand reliability without compromise, this hose integrates seamlessly into charge air cooler (CAC) piping networks.

Constructed from high-grade reinforced silicone, the 4-inch inner diameter accommodates substantial airflow volumes typical of aggressive turbo setups while the 7-inch length provides flexible routing through tight engine compartments. The reinforcement layers resist collapse under boost loads and prevent flex-induced leaks at clamp points—critical for maintaining consistent intercooler efficiency. Black finish resists UV degradation and heat checking, ensuring longevity in high-temperature environments where standard rubber compounds fail. The smooth inner bore minimizes turbulence and pressure drop, preserving boost response and charge density.

This hose segment suits both OEM CAC replacement and custom intake manifold plumbing for LS, EJ, K-series, and other popular platforms running single or twin turbo configurations. Mechanics and fabricators choose Vibrant Performance silicone for its ability to handle sustained 25+ psi boost without degradation or seepage. Pair with quality silicone clamps and matching hose diameters to ensure airtight connections; inspect regularly for cracks or softening as part of routine turbo maintenance intervals.
