Subaru 20B-79430-H1 OEM Ignition Coil C Cylinder 3 Coil-On-Plug

The Subaru 20B-79430-H1 is a genuine OEM ignition coil, designated Ignition Coil C, designed as a direct-fit coil-on-plug (COP) replacement for compatible Subaru engines. As a factory-original component, it meets the exact electrical and mechanical specifications set by Subaru, ensuring reliable spark generation and consistent engine performance.

Ignition coils in a COP system are responsible for converting low-voltage battery current into the high-voltage pulse required to fire the spark plug. A failing coil can result in misfires, rough idle, reduced fuel economy, and illuminated check engine lights. Replacing with a genuine Subaru coil restores factory ignition timing accuracy and combustion efficiency.

Key Features:

• Genuine Subaru OEM part — not aftermarket
• Designated Ignition Coil C (Cylinder 3 position)
• Coil-on-plug (COP) design for direct installation over the spark plug
• Engineered to meet factory electrical output and thermal specifications
• Ensures proper spark timing and combustion reliability
• Direct OEM replacement — no modifications required

This coil is sold as a single unit. Always consult your vehicle's service manual to confirm the correct coil position and torque specifications during installation. For multi-coil failures, Subaru recommends inspecting all coils in the set.
