Pertronix Flame-Thrower Ignition Coil — 40,000V Black, 1.5Ω High-Output Oil-Filled Upgrade

The PerTronix Flame-Thrower Ignition Coil 40011 is a high-output, oil-filled coil that produces up to 40,000 volts to deliver a stronger spark for improved combustion and throttle response in 6- and 12-volt inductive ignition systems.

If your engine is running on a points-style or electronic inductive distributor and you want a straightforward performance upgrade, this PerTronix Coil is engineered to provide a notable boost in spark energy without modifying your existing ignition system. Built to be a drop-in enhancement for many classic and modern vehicles, the Flame-Thrower coil combines a compact round canister design with oil-filled construction to help manage heat and maintain reliable spark delivery during normal street use.

How does this coil improve engine performance?

This coil raises the available secondary voltage to produce a hotter, more consistent spark, which helps ignite the air/fuel mixture more completely under many driving conditions. That can translate into crisper throttle response and smoother running, especially on systems that were limited by a weak stock coil.

• Up to 40,000 volts of secondary output for stronger ignition energy
• 1.5 ohm primary resistance tuned for inductive ignition systems
• Better combustion consistency at low and mid-range RPMs

Will this work with my existing Ignitor or distributor system?

The Flame-Thrower 40011 is optimized for PerTronix Ignitor electronic modules but is also compatible with most conventional points and electronic inductive distributor setups. It functions with both 6-volt and 12-volt systems when paired with the correct wiring and ignition components.

• Designed to mate with PerTronix Ignitor systems for best results
• Compatible with many points-style and electronic inductive distributors
• Works in both 6V and 12V applications when used as intended

What are the construction and mounting recommendations?

This coil uses an oil-filled round canister to assist heat dissipation and promote consistent spark output. Correct orientation is critical: install vertically with the electrical terminal upward to prevent oil leakage and internal damage; do not mount upside down or horizontally.

• Oil-filled canister for improved thermal behavior and durability
• Round housing designed for steady spark delivery during street use
• Vertical installation required — terminal pointing upward only

Is this a simple replacement for a factory coil?

Yes — the Flame-Thrower 40011 is intended as a direct performance upgrade for many factory coils and can usually be installed without modifying the distributor or wiring beyond standard connector swaps. However, verify primary resistance and system compatibility before swapping components to ensure proper operation.

• Direct upgrade path from many stock coils, no major modifications needed
• Check primary resistance (1.5 ohm specification) for system match
• Follow manufacturer wiring and grounding practices for best reliability

Who this product is for: The PerTronix Flame-Thrower Ignition Coil 40011 is aimed at classic car owners, restomod builders, and anyone maintaining or upgrading a points-style or electronic inductive distributor ignition who wants a reliable, higher-output coil. It suits drivers seeking improved throttle response and more dependable spark energy for everyday street use, provided they follow the vertical installation guidance and confirm electrical compatibility with their vehicle’s ignition system.
