The Spectre 4-inch PVC intake coupler elbow connects two 4-inch outside-diameter tubes at a tight 90-degree angle and includes two stainless steel worm-gear hose clamps for installation. Constructed from black PVC, it’s intended to join intake sections where a compact elbow is needed. This non-pressurized coupler is suitable for custom intake routing but not recommended for turbocharger or supercharger outlet connections.
