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

The CAC Hose 4in I.D. x 7in long in black is a straight silicone coupler designed for turbocharger and supercharger intercooler applications on modified vehicles. This tubing coupler serves as a critical connection point in charged air cooling systems, bridging intake manifold runners to intercooler cores or charge pipes. Whether you're building a forced-induction street car, performance truck, or high-boost race engine, a reliable CAC hose for sale ensures consistent boost delivery and cooler intake air temperatures—essential for maximizing horsepower and protecting engine internals from detonation.

Constructed from durable silicone material, this hose features a 4-inch inner diameter and 7-inch length, making it ideal for tighter engine bay layouts or as a transition section between larger diameter pipes. The straight, hump-style design provides a smooth airflow path while the silicone construction resists cracking from thermal cycling—a common failure point in stock rubber hoses exposed to turbo heat. Black silicone hoses also resist UV degradation and coolant absorption, ensuring long service life even in underhood environments exceeding 200°F. The specifications—weighing 0.95 lbs and measuring 9 x 4.25 x 14 inches when packaged—reflect a lightweight yet rigid construction suitable for both street and competition use.

Mechanics and tuners favor this CAC hose specifications for custom intercooler piping kits, allowing flexible routing around engine accessories and turbo manifolds. It pairs seamlessly with T-bolt clamps or band clamps (sold separately) at both ends, and the 4-inch bore accommodates most aftermarket charge pipe systems. Installation requires no special tools—simply slide over 4-inch ID pipes, secure with clamps, and route clear of moving belts and hot components. This hose is compatible with single and twin-turbo builds, as well as supercharged applications where intercooler plumbing demands compact, reliable connections.
