Pertronix Flame-Thrower II 12V Ignition Coil — Black Epoxy, 45,000V High-Voltage, 0.6Ω

The Pertronix Flame-Thrower II 45111 is a high-voltage 12V canister ignition coil that delivers up to 45,000 volts with a low 0.6Ω primary for stronger sparks and improved ignition reliability.

Built to upgrade both classic distributor-based systems and electronic conversion kits, this compact coil produces a taller, more consistent spark gap while maintaining a clean, stock-style appearance. Finished in black epoxy, the Flame-Thrower II fits under most engine covers and pairs directly with Pertronix Ignitor II and many inductive distributor ignition systems. It’s engineered to provide dependable, repeatable performance across varied driving conditions without requiring complex recalibration.

How does this coil improve engine starting and throttle response?

The increased secondary voltage helps create a hotter, more reliable spark that ignites the air/fuel mixture more completely. That often translates into faster engine starts, crisper throttle transitions, and fewer misfires under load. These gains are most noticeable when replacing an aged or low-output coil.

• 45,000-volt secondary for a larger spark plug gap
• Stronger ignition reduces misfires and improves cold starts
• Consistent output across RPM range for smoother throttle response

Will it work with my Ignitor II conversion or a conventional distributor system?

Yes—this coil is specifically optimized to pair with Pertronix Ignitor II modules but is also compatible with most inductive distributor systems. Its low 0.6Ω primary resistance allows easy integration without special resistors in many setups. Always check your vehicle’s electrical requirements and wiring before installation.

• Designed for plug-and-play use with Ignitor II kits
• Works with many factory-style distributors and inductive ignition modules
• 12V design fits standard automotive electrical systems

What installation or fitment considerations should I know?

The Flame-Thrower II is sized to replace most canister-style coils and uses standard mounting and terminal locations. Installation is straightforward: secure the coil, connect primary terminals to the module or distributor, and route the high-voltage lead to the distributor cap or coil tower. If your vehicle uses a ballast resistor or unique wiring, verify compatibility before final wiring.

• Standard canister dimensions for easy replacement
• Primary terminals accept common ring or spade connectors
• Black epoxy finish resists corrosion and blends with engine bays

How does finish and build affect durability and appearance?

The black epoxy coating protects internal windings while keeping a subdued, factory-correct look under the hood. Pertronix also offers chrome finishes if you prefer a polished aesthetic; the choice doesn’t change electrical performance. Rugged construction helps the coil withstand engine-bay heat and vibration for long-term reliability.

• Black epoxy resists moisture and engine contaminants
• Robust internal winding and insulation for sustained output
• Available in other finishes to match engine styling

Who is this for: The Pertronix Flame-Thrower II 45111 is aimed at enthusiasts and technicians who want a straightforward ignition upgrade for classic cars, street rods, or daily drivers that still use a distributor or are converting to Pertronix electronic ignition. It’s a good choice when you want higher voltage, reliable performance, and a near-stock appearance without extensive modifications.

• Key specs: 45,000 V secondary, 0.6 Ω primary, 12 V operation, black epoxy finish.
• Compatibility: Pertronix Ignitor II, many inductive distributor systems, plug-and-play distributors.
