Pertronix Flame-Thrower II Ignition Coil 45,000V 0.6 Ohm - Reliable

Our review of the Pertronix Flame-Thrower II ignition coil finds it best suited to enthusiasts upgrading an older ignition system or anyone fitting a Pertronix Ignitor II conversion. The single biggest reason to buy is its combination of high voltage output and ultra low resistance, which produces a strong, consistent spark that often feels like a clear improvement over many stock OEM coils. Installation is straightforward for those familiar with ignition work and it pairs especially well with Pertronix modules and plug-n-play distributors.

Key Features

• Ultra low resistance: The 0.6 ohm primary resistance reduces dwell losses and is suitable for both inductive and CD ignition systems, helping to improve spark energy.
• High voltage output: Delivers up to 45,000 volts to the plug, which promotes reliable ignition and better combustion stability under load.
• 12 volt design: Built for standard 12 V vehicle electrical systems so it installs without needing special power supplies.
• Finish options: Available in black or chrome-plated finishes so builders can maintain a stock or customized engine appearance.
• Ignitor II compatibility: Specifically engineered to integrate seamlessly with Pertronix Ignitor II electronic ignition conversion kits for trouble-free operation.
• Engineered for performance: Designed to complement Pertronix Ignitor conversions and plug-n-play distributors to maximize ignition efficiency.

Who It's For

This coil is aimed at DIY mechanics, restorers, and performance-minded owners who are converting to an electronic ignition or replacing a weak OEM coil. It is particularly valuable for those already using Pertronix Ignitor modules or plug-n-play distributors, where compatibility and matched performance are important.

It is less appropriate for someone who needs a coil with very long-term proven heavy-duty durability for extreme motorsport use; while customer feedback praises performance and fit, some users note mixed durability impressions, so racers seeking frequent high-stress longevity testing may prefer purpose-built motorsport coils.

Pros & Cons

Pros

• Strong 45,000 V output provides a noticeable improvement in spark quality over many stock coils.
• Low 0.6 ohm primary resistance works with inductive and CD systems and complements Pertronix modules.
• Clean appearance with black or chrome finishes that match engine aesthetics.
• Easy to install and a good value for owners converting to electronic ignition.

Cons

• Some users report mixed durability impressions, so long-term reliability under extreme conditions is less documented.
