Manifold Flange Adapter

HARDDRIVE Manifold Flange Adapter

Upgrade your carburetion with precision. The HARDDRIVE Manifold Flange Adapter converts older two-bolt flange style intake manifolds to accept modern Mikuni HSR and late-model Keihin CV carburetors, delivering reliable fitment and improved performance.

• Precision machined: CNC billet aluminum construction for accurate dimensions and long-lasting durability.
• Direct conversion: Allows hassle-free installation of Mikuni HSR and late Keihin CV carbs on legacy two-bolt manifolds.
• Corrosion resistant: Lightweight aluminum resists rust and stands up to heat and vibration.
• Easy installation: Bolt-on design uses existing flange pattern — minimal modification required.

Perfect for custom builds, restorations, and performance upgrades, the HARDDRIVE Manifold Flange Adapter ensures a secure seal and precise carb alignment for smoother throttle response and consistent fueling. Compatibility: older two-bolt flange manifolds to Mikuni HSR & late Keihin CV carburetors.
