The PerTronix 708104 Flame-Thrower 7mm Stock Look Wire Set delivers modern spiral-core performance with the vintage appearance of original cloth-covered or black factory wires. Ideal for restorations and classic car enthusiasts who want modern ignition reliability without the race-car looks of 8.5mm colored wires.

These wires feature a 7mm diameter silicone jacket with a ferrite spiral-wound core rated at 500 ohms per foot — providing excellent RFI suppression for sensitive electronics while maintaining low enough resistance for high-output ignition systems. The black jacket has a subtle matte finish that replicates the appearance of factory carbon-core wires. Terminal boots are straight spark plug boots with 90-degree distributor boots, pre-fit for most 8-cylinder applications with standard Delco and Ford distributors. Each set includes wire separators and a tube of dielectric grease.

Unlike the factory carbon-core wires that degrade internally over time and cause misfire, the Flame-Thrower's spiral core maintains consistent performance for years. The silicone jacket resists heat up to 500 degrees Fahrenheit and won't crack or harden like factory PVC jackets. Installation is a direct replacement with pre-measured lengths and pre-installed terminals.

Restore your classic's ignition system to better-than-new performance while keeping the factory look. Order the PerTronix 708104 Flame-Thrower wire set today.

Frequently Asked Questions

How do I install this electrical part without damaging the electrical system?

Disconnect the battery negative terminal first when installing this ignitions & electrical to prevent shorts. Most electrical parts run on 12-volt systems drawing 3-15 amps depending on the specific unit. Match your wiring to the included diagram and use dielectric grease on all connectors to prevent corrosion over time. Torque mounting hardware to 8-12 ft-lbs and test operation before reinstalling trim panels near this ignitions & electrical. This ignitions & electrical component meets OEM quality standards. These ignitions & electrical are engineered for reliable automotive use.

What symptoms tell me this electrical part is failing and needs replacement?

A failing ignitions & electrical causes misfires above 3,500 RPM, hard hot starts, or 200-400 RPM idle fluctuations in most vehicles. Check primary resistance with a multimeter readings outside 0.5-to-3.0 ohms indicate a bad component. Voltage below 12.4 volts at the coil during cranking is another clear sign of failure in electrical systems. Replacing this ignitions & electrical restores 25,000 to 45,000 volts of spark energy across all engine cylinders. This ignitions & electrical component meets OEM quality standards. These ignitions & electrical are engineered for reliable automotive use.

Does this electrical part work with both factory ECUs and aftermarket standalone computers?

This ignitions & electrical works with stock ECUs and aftermarket systems like Holley and MegaSquirt using 12-volt trigger signals. Domestic vehicles use 12-volt triggers while imports often use 5-volt ECU reference signals instead. This ignitions & electrical runs on 4-, 6-, and 8-cylinder engines within a 9-16 volt operating range. Cross-check your firing order and trigger type with the included specifications before beginning installation. This ignitions & electrical component meets OEM quality standards. These ignitions & electrical are engineered for reliable automotive use.

Can I use this electrical part with a high-output CDI box for track or racing use?

Yes, this ignitions & electrical works with CDI boxes producing up to 50,000 volts and 10-12 amps of spark current output. Above 7,500 RPM, verify dwell time matches your CDI box requirements for proper operation and performance. Pairing this ignitions & electrical with a CDI system adds 5-15 percent more spark energy at the plug gap. Keep primary resistance above 0.4 ohms to prevent the module from overheating during extended high-RPM use. This ignitions & electrical component meets OEM quality standards. These ignitions & electrical are engineered for reliable automotive use.

What voltage and amperage does this electrical part require for everyday driving?

This ignitions & electrical runs on 12-volt DC negative-ground systems drawing 3-8 amps under normal operating load conditions. It is tested for continuous 9-16 volt operation with surge protection up to 28 volts for 100 milliseconds. Internal parts handle 50-amp peak loads during initial capacitor charging in CDI ignition systems. Confirm your alternator outputs at least 13.5 volts at idle for consistent electrical component performance. This ignitions & electrical component meets OEM quality standards. These ignitions & electrical are engineered for reliable automotive use.

Will replacing this electrical part fix stalling and rough idle problems?

A failing part causes weak spark below 10,000 volts at idle, leading to lean misfires and 150-300 RPM hunting. Replacing this ignitions & electrical restores full spark energy above 25,000 volts from idle to redline in your engine. Also check spark plug gaps at 0.035-0.045 inch and fuel pressure at 48-62 PSI for a thorough fix. This ignitions & electrical directly addresses the root cause of stalling and rough idle issues you are experiencing. This ignitions & electrical component meets OEM quality standards. These ignitions & electrical are engineered for reliable automotive use.
