Stock coils are notorious for falling off as rpm goes up. However, the Screamin' Demon Coil by Performance Distributors is designed to produce hotter spark throughout the entire RPM range with virtually no drop in power. Open up spark plug gaps to an amazing .065" with the Screamin' Demon Coil. The longer duration spark it produces burns your fuel more efficiently. 


The coil has a brass terminal rather than aluminum, which provides better conductivity and will resist corrosion longer. Your spark plugs will stay cleaner. The Screamin' Demon coil is easy to install, mounting in the original equipment location.

  • No drop in power as rpm's increase
  • Opens spark plug gaps to .065"
  • Burns your fuel more efficiently
  • Brass terminal provides better conductivity
  • Resists corrosion longer than stock coils
  • Easy to install

Because the Screamin' Demon is too "hot" for stock plug wires, high-performance wires are highly recommended.  For best performance, we recommend using this high-performance coil in combination with a performance cap and rotor, Dyna-Module, and a set of performance wires.

Screamin' Demon Coil

I noticed immediate results once this quality coil was installed. Both in accelleration and MPG. Installed the E3 plugs and Magnecor wire set as well. Impressed with the quality and ease of installation. Highly recommend!
