Flame-Thrower III Coil - Black - Oil Filled

The Flame-Thrower III Coil in Black from Pertronix Ignition represents a modern evolution in high-performance ignition technology designed for enthusiasts and mechanics upgrading classic and contemporary engines. Built as an oil-filled ignition coil, this component delivers the robust spark energy required for precision tuning, stronger combustion, and improved throttle response across a wide range of engine platforms. Whether you're restoring a vintage muscle car, optimizing a street rod, or fine-tuning a performance engine build, the Flame-Thrower III provides the reliable, high-voltage output that separates mediocre ignition systems from championship-level performance.

The oil-filled construction of the Flame-Thrower III Coil offers superior thermal management and dielectric insulation, critical factors in maintaining consistent spark timing under high heat and load conditions. Unlike conventional air-core designs, oil-filled coils dissipate heat more efficiently, reducing voltage degradation during sustained high-RPM operation and extended driving sessions. The compact 3.5 x 2.75 x 7.5-inch profile makes this coil ideal for tight engine bay installations common in retrofits and custom builds, while its 1.67-pound weight ensures minimal impact on engine balance and accessory drive systems. Pertronix Ignition's engineering focuses on delivering maximum amperage output and precise dwell time control, resulting in cleaner idle characteristics, faster engine response, and improved fuel economy across the RPM band.

Mechanics and engine builders favor the Flame-Thrower III Coil for both carbureted and fuel-injected applications where OEM ignition systems fall short of performance demands. Installation requires verification of coil polarity and proper secondary lead routing to maximize spark plug performance and eliminate misfires across load ranges. The black powder-coated finish resists corrosion and maintains a professional appearance in engine bays exposed to salt spray, moisture, and thermal cycling. Proper mounting and secure electrical connections are essential to prevent vibration-induced failures and ensure years of reliable operation in competition, street performance, or daily-driver applications.
