Flare Plugs; Size: -6 AN

The Vibrant Performance -6 AN Flare Plugs are precision-engineered fittings designed for high-performance fuel, oil, and coolant systems where reliable sealing is essential. These hex-head aluminum plugs serve as terminal closures in AN (Army-Navy) port applications, preventing fluid leaks and maintaining system integrity under pressure and vibration. Whether you're building a custom engine bay, restoring a classic hot rod, or maintaining a race-ready vehicle, these -6 AN flare plugs are essential components for any serious automotive or powersports enthusiast.

Manufactured from lightweight aluminum and finished in black anodized coating, these plugs resist corrosion while maintaining a superior strength-to-weight ratio—critical for motorsports applications. The hex head design provides a secure grip for proper installation torque without stripping, while the -6 AN thread standard ensures compatibility with industry-standard -6 AN fittings and hose assemblies. The anodized finish protects against oxidation in harsh underhood environments, salt air, and fluid exposure, extending component lifespan and maintaining aesthetic consistency across custom installations.

Each plug is engineered to withstand the thermal cycling and pressure fluctuations inherent in modern performance engines. These -6 AN flare plugs are ideal for fuel line termination, oil cooler block-offs, and vacuum-line dead ends in custom fuel injection systems, race car builds, and high-performance modifications. They are a must-have for anyone looking to enhance the reliability and performance of their automotive systems.
