Pertronix Flame-Thrower II Ignition Coil — 45,000V 0.6Ω, 12V Black Epoxy for Inductive Distributors

The Pertronix Flame-Thrower II 45111 is a high-output 12‑volt ignition coil delivering up to 45,000 volts with a 0.6 ohm primary for stronger sparks and improved drivability.

This compact black-epoxy coil is engineered to upgrade classic and modern inductive distributor systems and pairs especially well with Pertronix Ignitor conversion kits. It provides the extra voltage needed to support wider spark plug gaps and more reliable combustion across a variety of engines while maintaining a factory-friendly appearance.

How does this coil improve engine spark and throttle response?

The Flame-Thrower II raises secondary voltage to produce a fuller, hotter spark that helps more consistently ignite the air/fuel mixture. That stronger spark can reduce misfires at higher gaps and can make throttle transitions smoother under load.

• 45,000 volts secondary output for larger spark plug gaps
• 0.6 ohm primary resistance for higher energy transfer
• Works with inductive distributor systems to boost spark intensity

Will this coil fit my Pertronix Ignitor or distributor setup?

The 45111 is designed to be compatible with Pertronix Ignitor II conversion kits and most inductive-type distributors. It integrates cleanly into plug‑and‑play installations while keeping the stock mounting footprint in many applications.

• Direct compatibility with Ignitor II electronic conversion kits
• Low primary resistance makes it suitable for a wide range of inductive systems
• Available in black epoxy finish to preserve a factory look

What practical installation and durability features does it offer?

The unit uses a robust epoxy housing that resists vibration and environmental exposure common in engine bays. Its wiring terminals and form factor are sized to match standard coil mounts, making swap‑outs straightforward for most hobbyists and professional installers.

• Black epoxy finish for corrosion resistance and discreet appearance
• Standard electrical terminals for quick installation
• Engineered for dependable operation with Pertronix electronic ignition products

Can this coil help with fuel economy or performance tuning?

While results vary by engine and tuning, a more consistent spark can lead to more complete combustion and smoother engine behavior. That improved combustion efficiency may help in setups where ignition weakness previously caused rough running or reduced power.

• Stronger spark can support leaner mixtures more reliably
• May reduce misfires that degrade fuel economy and power
• Useful when optimizing gap size for performance applications

Who this is for: The Pertronix Flame-Thrower II 45111 is aimed at classic-car restorers, hot‑rodders, and anyone upgrading an inductive distributor to a higher-output coil—especially those using Pertronix Ignitor conversion kits. Choose this coil if you want a discreet black housing, simple installation, and higher secondary voltage for improved ignition performance without changing your vehicle’s original appearance.
