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

Our review of the Pertronix Flame-Thrower II ignition coil finds it best suited for tuners and DIY mechanics who want a clear, measurable upgrade over many stock coils. The single biggest reason to buy is its combination of an ultra low resistance 0.6 ohm primary and a high 45,000 volt output, which together deliver a stronger, more consistent spark when paired with inductive or CD ignition modules. Installation is straightforward and the chrome finish lets the coil look at home in restorations or show-quality engine bays.

Key Features

• Low primary resistance: The 0.6 ohm primary resistance is designed to work with both inductive and CD ignition systems to improve coil charge and spark energy.
• High voltage output: The 45,000 volt peak output produces a strong spark that can improve combustion consistency and throttle response compared with many OEM coils.
• Compatibility with Ignitor II: Built for seamless integration with Pertronix Ignitor II conversion kits, making system matching simple for electronic ignition upgrades.
• Finish options: Available in chrome-plated or black finishes so the coil can either match a restored stock look or blend with a darker engine bay aesthetic.
• Designed for performance kits: Engineered to complement Pertronix Ignitor conversion kits and plug-n-play distributors for a reliable upgrade path.

Who It's For

This coil is ideal for owners of classic cars, hot rods, or marine engines who are installing an electronic ignition module or converting from points to an electronic system. It suits people who want a visible upgrade in spark consistency and an attractive chrome appearance that fits restoration projects.

It is less appropriate for those seeking a direct OEM-spec replacement for every original application where exact factory resistance is required, or users who prioritize absolute long-term durability data over immediate performance gains; some buyers have noted mixed comments about longevity in heavy-duty marine use.

Pros & Cons

Pros

• Noticeably stronger spark performance when paired with Pertronix ignition modules.
• Low 0.6 ohm primary resistance supports both inductive and CD systems for broad compatibility.
• Attractive chrome finish that fits show-quality engine bays while offering a black option for a subdued look.
• Easy to install and a clear upgrade over many stock coils in real-world installs.

Cons

• Durability received mixed feedback from some customers, so those needing extended heavy-duty marine duty should verify fit and duty cycle first.
