The Holley EFI 566-103 is a precision-machined billet aluminum blank distributor cap designed as a replacement or service component for Holley's Dual Sync Distributor systems. This cap features a sleek black anodized finish and provides a clean, sealed top for distributors that don't require traditional spark plug wire terminals.

Key Features:

• CNC-machined billet aluminum construction for durability and precision fit
• Black anodized finish for corrosion resistance and professional appearance
• Blank design with no terminal openings - ideal for crank trigger or coil-per-cylinder applications
• Direct replacement for worn or damaged caps on Holley Dual Sync Distributors
• Compatible with Holley 565-111 and all 565-200 series Dual Sync Distributors

This replacement cap is essential for maintaining the integrity of your distributor housing when running distributorless ignition systems or when the distributor is used solely for camshaft synchronization. The precision-machined design ensures a proper seal and professional finish for your engine bay.
