4in Intake Tube 90 Deg

The 4in Intake Tube 90 Deg by SPECTRE is a precision-engineered air intake component designed for custom automotive builds and engine modifications. This 90-degree elbow tube serves as a critical junction point in high-flow intake systems, allowing builders and mechanics to route cold air induction from the filter box directly into the throttle body or carburetor at an optimal angle. Whether you're fabricating a custom intake manifold, upgrading to a performance air filter setup, or designing a clean engine bay layout, this component provides the flexibility and durability needed for professional-grade installations.

Constructed with durable material and precision 90-degree geometry, the 4in intake tube maintains smooth airflow transition while minimizing turbulence and velocity loss during intake strokes. The four-inch diameter accommodates substantial air volume, making it suitable for both naturally aspirated and forced-induction applications where maximum breathing capacity is essential. At 1.45 lbs, the tube adds minimal weight to your intake system while delivering the structural integrity required in high-performance environments. The compact dimensions (7 x 4.5 x 12 inches) facilitate easy fitment in tight engine bays without requiring extensive fabrication or rework of surrounding components.

Mechanics and fabricators benefit most from this component when building custom air intake systems, upgrading factory induction pathways, or creating engine swaps that demand flexible ducting solutions. The 90-degree configuration is ideal for transitioning from horizontal filter mounting to vertical throttle body positions, or for adapting aftermarket filter housings to existing carburetors without modification. Installation is straightforward for those with basic mechanical skills, though professional installation is recommended to ensure proper clamp torque, seal integrity, and optimal airflow characteristics in your specific application.
