Pertronix Flame-Thrower Ignition Coil 40011 Black — 40,000V Oil-Filled High-Output

The PerTronix Flame-Thrower Ignition Coil 40011 is a high-output, oil-filled 40,000‑volt coil engineered to boost spark energy and deliver more consistent ignition in compatible 6 and 12‑volt inductive electronic systems.

This compact, black canister coil is built as an aftermarket upgrade for vintage and modern vehicles that use inductive distributor ignitions, including systems using PerTronix Ignitor modules. Its 1.5 ohm primary resistance and oil-filled construction are intended to improve spark intensity and heat management compared with many stock coils. Proper vertical mounting with the terminal up preserves the oil seal and ensures reliable operation.

How does the Flame-Thrower coil affect starting and throttle response?

The higher secondary voltage can create a stronger, more consistent spark, which often helps ignite the air/fuel mixture more completely. That can translate into firmer starts and crisper throttle transitions on vehicles that benefit from enhanced spark energy.

• Delivers up to 40,000 volts for increased spark potential
• 1.5 ohm primary for compatibility with inductive electronic ignitions
• Improved combustion consistency under typical street driving

Will this coil work with my 6‑volt or 12‑volt ignition system?

Yes — the Flame-Thrower 40011 is designed to perform in both 6V and 12V inductive electronic distributor systems. It is optimized for use with PerTronix Ignitor modules but also fits many conventional points or electronic inductive distributors.

• Works in both 6V and 12V systems when used with inductive ignitions
• Compatible with PerTronix Ignitor systems and many aftermarket modules
• Designed as an upgrade replacement for many stock coils

What installation details and precautions should I follow?

The coil is oil-filled, so orientation matters: always mount it vertically with the electrical terminal facing upward. Avoid horizontal or upside-down mounting to prevent oil leakage and potential internal damage. Use proper wiring, secure mounting, and correct ground connections for best reliability.

• Mount vertically; terminal up to prevent oil leakage
• Use correct wiring and secure connections to the distributor or module
• Follow torque and clearance guidance to avoid heat or vibration issues

How durable is the Flame-Thrower coil for street-driven vehicles?

The oil-filled canister aids in heat dissipation and stability under normal street use. While robust for everyday driving, longevity depends on correct installation, electrical compatibility, and avoiding extreme mounting or exposure to contaminants.

• Oil-filled design helps manage coil temperature during operation
• Round canister resists vibration when securely mounted
• Performance and life improved when matched to compatible ignition modules

Who this is for: The PerTronix Flame-Thrower 40011 is aimed at classic car owners, restorers, and hobbyists seeking a straightforward ignition upgrade for 6V or 12V inductive distributor systems. It suits anyone using a PerTronix Ignitor or similar electronic conversion who wants stronger spark energy without altering the rest of the ignition system. If you need maximum compatibility, consistent street performance, and follow the vertical-mounting requirement, this coil is a practical, easy-to-install upgrade option.
