About this item

  • High voltage enables you to run larger spark plug gaps for added power and improved fuel economy
  • Designed to mate with the Ignitor Electronic Conversion Kit, but can benefit virtually any distributor type inductive systems.
  • Rated at 40,000 volts with 3.0 ohms of resistance
  • Black, oil-filled canister style coil.
  • Legal in all 50 states and Canada (CARB EO #D-57-21)


While it’s the perfect coil to go with the PerTronix Ignitor breakerless ignition, our 40,000 volt Flame-Thrower canister coil can benefit virtually any distributor type inductive system. Its higher voltage allows largerspark plug gaps for added power, smoother response and better fuel economy. These coils are internally resisted so installation and wiring is drastically simplified. Our oil filled coils offer great heat control for street driven vehicles, while our epoxy filled coils provide superior winding support for high vibration environments in off-road vehicles and boats.

Anyone can install this, takes 5 minutes and is super easy. 2 nuts taken off, wires attached, nuts screwed on, plug pushed in. Once installed it will just work in the background, never needing to be messed with again. Required with some aftermarket distributors. Make sure you get the right ohm.Downside - Requires ballast resistors removed or your car wont want to start. That can be tougher than you think depending on your car. My ignition wire was a ballast resistor wire and I had to replace the whole wire from key to engine bay, not an easy task for a rear engined car. Had to go under the glued down carpet, then through the doublewalled firewall. Most cars probably dont have to worry about this, but if yours does be prepared.

This coil was recommended for installation of PerTronix HEI. Word of note: When installing the PerTronix HEI system in the distributor , measure the height of the rotor from the rotor point of contact, to the distributor plate BEFORE removing the distributor plate with the points. Some after market point sets have a rotor that will measure a little taller than OEM. The magnet that mounts on the distributor bumps will make an aftermarket rotor sit .060 higher inside the distributor cap, thus internally destroying the cap. Measure the height of the rotor AGAIN after installing the PerTronix HEI system !! The engine in my boat has never run THIS GOOD! Drove the boat 36 miles up the Missouri River, and 36 miles back. That's 72 miles round trip on a river, without one single hiccup. Great product.

Purchased for a four cylinder Pertronix distributor. Lower OHM coil will work, but shirtens life of pick up.

I bought this coil so I could eliminate the resistor with my electronic distributor. Started the car with it for the first time today. Fired right up with no issues. This was also the recommended coil for my application.

Muchas personas piensan que solo funciona con los módulos de Ignitor 1 de Pertronix, sin embargo, también es una buena opción para reemplazar la vieja bobina que usas en tu automóvil con platinos!

Excelente artículo les ayudará mucho para los que andan modificando sus Vochos para una mejor respuesta de encendido, en mancuerna con el distribuidor de la misma marca, es una gozada

Just recently installed a PERTRONIX (40511) 3 ohm coil on a 4AGE BIGPORT and there is quite a noticeable difference with the power. Low down torque slightly increased and a smoother delivery of power through the rev range. Was using a BOSCH SU12 before and it was good but installing the PERTRONIX gave the engine a SLIGHT increase of power. Highly recommend if you want to replace your OEM coil unit.AAA+++
