Pertronix Flame-Thrower III Ignition Coil 45,000V Black (44011) 0.32Ω High-Output

The PerTronix Flame-Thrower III 45,000 Volt ignition coil (model 44011) is a high-output, ultra-low-resistance coil engineered to deliver faster charge times and stronger spark energy for modern 12V electronic ignition systems.

Designed for performance engines and high-current electronic ignitors, this coil combines a 0.32 ohm primary resistance with up to 45,000 volts of secondary output. It’s tuned to support rapid charging and sustained spark intensity at elevated RPMs, making it a common upgrade for racers, hot-rodders, and anyone running PerTronix Ignitor III or compatible capacitive discharge systems. Note: this coil is not suitable for breaker-point or standard inductive modules, and correct vertical installation is essential to avoid oil leakage.

How does the Flame-Thrower III improve throttle response?

Lower primary resistance shortens the coil’s charge interval, letting the ignition system reach peak current faster. Faster charge cycles maintain stronger spark at higher engine speeds, which helps more consistent combustion across the rev range without changing spark plug or timing settings.

• 0.32 ohm primary for rapid charge times
• Up to 45,000 volts of spark energy for reliable ignition
• Sustains spark intensity at elevated RPMs
• Optimized for high-current electronic ignition systems

Will this coil work with my electronic ignition or CD system?

The Flame-Thrower III is optimized for PerTronix Ignitor III and many capacitive discharge (CD) systems thanks to its low-resistance design. It is not compatible with breaker-point ignitions or standard inductive modules—using it with those systems can reduce reliability or damage components.

• Compatible: Ignitor III and many CD systems
• Not compatible: breaker points and standard inductive modules
• Designed for 12V electronic ignition applications
• Check system current draw and installation orientation before fitting

What installation tips ensure reliable operation?

Proper mounting orientation is critical: install the coil vertically with the terminal facing upward to prevent oil leakage and internal damage. Use secure high-temperature wiring and correct mounting hardware, and verify clearances so heat and vibration won’t stress connections.

• Mount vertically with terminal up—never upside down or horizontal
• Use high-temp ignition wire and proper connectors
• Securely fasten coil to reduce vibration-related failures
• Confirm compatibility with your ignition module before installation

What performance gains can I realistically expect?

Expect crisper, more consistent sparks at higher RPMs and improved ignition stability under load, especially in engines with modified cam timing, higher compression, or increased fuel demands. While results vary by application, the coil’s rapid charge and high output support better throttle response and reduced misfires in demanding conditions.

• Stronger spark energy for improved ignition reliability
• Fewer miss or misfires at high engine speeds
• Better throttle response under load
• Works best as part of a matched high-current ignition package

Who is this for? The PerTronix Flame-Thrower III 44011 is aimed at performance enthusiasts, racers, and anyone upgrading to a high-current electronic ignition or CD system who needs faster charging, higher-voltage spark output, and a coil built to sustain spark intensity at elevated RPMs. If you run breaker points or a standard inductive module, choose a coil matched to those systems instead.
