Info

The cap and rotor of any ignition system must be considered mainte­nance items. Just as you change the oil and filter of your car, you should always replace the cap and rotor as a set. These replacement GM rotors are adjustable and come with the brass contact.

  • Injection molded from Rynite material for incredible strength and high dielectric properties
  • Stainless steel/brass rotor trip - screwed in place to handle extreme rpm and high heat conditions
  • Deep molded vanes to stir up the air inside the cap to prevent spark ionization
  • Screws are set deep in the housing to prevent spark scatter
