Universal Tube

The AIRAID INTAKE SYSTEMS Universal Tube is a premium 4-inch diameter intake hose engineered for custom air intake systems, engine modifications, and aftermarket tuning applications. Designed for builders, mechanics, and performance enthusiasts who demand flexibility in routing and component integration, this universal tube accommodates multiple bend angles—30, 45, 60, and 90 degrees—to fit diverse engine bay configurations. Whether you're fabricating a cold air intake, turbo inlet system, or custom engine breathing solution, this tube delivers the versatility required for professional-grade installations.

Manufactured with precision engineering, the Universal Tube maintains a consistent 4-inch internal diameter to ensure optimal air flow velocity and minimal restriction while supporting multiple bend geometries. The multi-angle design allows installers to select the exact configuration needed—whether 30-degree bends for gradual transitions, 45-degree angles for moderate routing, 60-degree bends for tighter clearances, or full 90-degree elbows for sharp direction changes. Weighing 5.7 lbs and measuring 24.2 x 5.4 x 36.8 inches, the tube is constructed to withstand pressure fluctuations common in forced induction and naturally aspirated high-performance applications while maintaining dimensional stability under thermal cycling.

Professionals and performance builders favor this Universal Tube for standalone installations, intake system upgrades, and OEM replacement scenarios across various vehicle platforms and engine types. The versatile bend-angle selection eliminates the need to purchase multiple specialized components, streamlining sourcing and reducing project costs. Installation requires standard clamp fittings compatible with 4-inch diameter hoses; proper sizing and secure clamping ensure air-tight seals and reliable long-term performance in both street and competition environments.
