MSD 5511 Street Fire Direct Ignition Coil Black Single

The MSD 5511 Street Fire Direct Ignition Coil is a high-performance, direct-fit replacement coil engineered to deliver stronger spark energy over stock ignition components. Designed for late-model GM LS-platform engines, this coil bolts directly into the factory location and plugs into the OEM connector — no wiring modifications required.

MSD engineers selected superior materials and optimized winding ratios to extract more spark energy from the coil's secondary circuit, resulting in improved combustion efficiency, quicker throttle response, and more consistent power delivery across the RPM range. The epoxy-filled E-core construction provides excellent resistance to heat, vibration, and moisture, ensuring long-term durability in demanding under-hood environments.

Key Features:

• 48,000 maximum volts — higher output than factory coils for a stronger, more reliable spark
• Epoxy-filled construction — protects internal windings from heat, vibration, and moisture
• E-core design — improved winding ratios for greater spark energy efficiency
• Direct OEM replacement — bolts in place of the factory coil with no modifications
• Factory connector compatible — accepts the original OEM plug for a clean, hassle-free installation
• Sold individually — single coil per package
• CARB E.O. #D-40-42 compliant
