In simple terms coils are rated by their primary resistance—less resistance in the primary windings of the coil allows more current to flow, which makes a stronger magnetic field. … Flame Thrower II coils have lower resistance, 0.6 ohms for use with Ignitor II ignition systems as well as many other high-energy ignitions.
Are all ignition coils the same?
Currently most all automotive ignition coils are application-specific and are not interchangeable from one manufacturer to another. If you are asking about a different type or use of an ignition coil then repost the question with the specifics.
How do I choose an ignition coil?
- Primary resistance,
- Turns ratio, and.
- Input voltage.
