Pertronix Flame-Thrower II 45,000V Ignition Coil, Black – 0.6Ω High-Output Vertical-Mount

Designed as an upgrade for modernized ignition systems, the Flame-Thrower II coil combines a low 0.6 ohm primary resistance with an oil-filled canister to support high-current inductive ignitions. Its round, vertical-mount construction focuses on consistent heat dissipation and reliable spark delivery under street driving conditions. This unit is black-finished and intended for use with PerTronix Ignitor II and Ignitor III modules, plus other high-current electronic ignitions that require lower primary resistance.

How does this coil improve ignition performance?

The Flame-Thrower II raises available spark energy by producing up to 45,000 volts, which helps produce a stronger spark when paired with compatible electronic ignition modules. That stronger spark can improve ignition reliability, especially under high-load or high-RPM situations on the street.

• High output: up to 45,000 volts for improved spark energy
• Low primary resistance: 0.6 ohm to support high-current modules
• Designed for inductive electronic ignitions, not breaker points

Will it fit my vehicle and electronic ignition setup?

This coil is built for systems that use low-resistance, high-current electronic modules such as PerTronix Ignitor II and Ignitor III. It is not intended for original breaker-point ignitions or older Ignitor I modules that require higher primary resistance.

• Compatible with Ignitor II and Ignitor III systems
• Works with other high-current inductive electronic ignitions
• Not recommended for breaker points or Ignitor I modules

What are the installation and mounting requirements?

Because the Flame-Thrower II is oil-filled, correct orientation is critical. Always install the coil vertically with the terminal facing upward to avoid oil leakage and internal damage, and ensure secure electrical connections following vehicle wiring and safety practices.

• Vertical mounting only — terminal up to prevent oil leakage
• Avoid horizontal or inverted installations to protect internal fill
• Use proper high-current wiring and secure mounting hardware

How does the coil’s construction support durability on the street?

The oil-filled canister design helps dissipate heat and maintain consistent spark delivery during typical street driving. The sturdy round shell and quality internal winding support repeated thermal cycles and sustained use without frequent degradation.

• Oil-filled for improved heat management and consistent performance
• Robust round canister resists environmental stressors
• Black finish for corrosion resistance and a clean under-hood look

Who is this for? The PerTronix Flame-Thrower II 45,000V coil is aimed at enthusiasts and mechanics upgrading factory ignition systems to higher-energy electronic modules, owners of classic or performance vehicles fitted with Ignitor II/III or similar high-current electronic ignitions, and anyone seeking a durable, oil-filled coil for reliable street operation. Avoid this coil if your setup relies on breaker points or older Ignitor I modules; instead choose a coil matched to higher primary resistance in those cases.
