Ignition


COIL ON PLUG (C.O.P)
This is the way many of the engine manufacturers and OEM's are moving for ignition coils. By placing the coil directly on the spark plug, the need for high voltage wires from the coil to the distributor to the spark plug is eliminated.

Forecast's units are thermal shock tested from -40 to 250 degrees. Unit's endurance is tested by operating at 250 degrees for up to 1,000 hours.

IGNITION COIL

Forecast prides itself on having the best coil coverage currently available in the industry. With new applications presently under development, Forecast import and domestic ignition coils are manufactured strictly to O.E.M. specification and feature the following:
  • Special-blend oil in oil-filled units to provide better heat dissipation, better performance, and longer life.
  • O.E.M-type epoxy material in new-style epoxy units for superior dielectric strength.
  • 100% copper wire in both primary and secondary windings for proven performance.
  • Units' thermal shock tested from -40 to 250 degrees. Units' endurance tested operating at 250 degrees for up to 1,000 hours.
  • Primary and Secondary windings with enamel magnet wire rating highest temperature available in the aftermarket.

CAPS

Forecast import and domestic distributor caps are manufactured to exact O.E.M. specification to ensure proper fit and function. Additionally, they offer the following high-performance features:
  • Polypropylene, PBT, or Thermoset molding material for maximum dielectric strength and resistance to carbon-tracking.
  • Brass, aluminum, stainless, or tin-plated terminals and inserts for superior conductivity and performance.
  • RFI resistors where specified by O.E.M. to eliminate radio static and potential ECU-damaging voltage spikes.
  • Vent-holes/vent-caps as utilized on O.E.M. units.
  • Molded-on firing order as specified by O.E.M.

Units are molded with high temperature and high die-electric plastics. Brass terminals on certain models surpass corrosion prone Forecast aluminum terminals in long term testing.

ROTORS

Manufactured to look and fit like the O.E.M. unit, Forecast import and domestic rotors are constructed from these high-performance materials:
  • Polypropylene, PBT, Moplen, or Thermoset molding material on rotor body for maximum dielectric strength.
  • Brass, stainless, or nickel-plated steel rotor vanes and shaft bushings for excellent conductivity and long wear.
  • O.E.M.-style shaft-retention clips where required for positive rotor-to-shaft retention.
  • R.P.M.-limiter where specified by Forecast to protect engine overrevving.
  • RFI resistor where specified by Forecast to eliminate radio static.

Units are molded with high temperature and high die-electric plastics. Brass terminals on certain models surpass corrosion prone Forecast aluminum terminals in long term testing.

IGNITION MODULES

Forecast modules are manufactured to O.E.M. specification. Each unit is carefully tested to ensure proper fit and function. Some of the features and benefits of Forecast modules are:
  • Proprietary circuit design. Forecast affiliate-manufacturers analyze the O.E.M. circuit and make appropriate modifications which offer improved circuit protection and longer unit life.
  • Laser-trimmed film resistors. This procedure offers extremely accurate electronic control while maintaining peak efficiency over a longer period of time.
  • High-temperature polymer housings. Use of this housing material reduces moisture ingress, and minimizes vibration damage which results in greater reliability for an extended period.
  • Units are tested from -40 to 250 degrees to assure functionality under all possible operating environments.
