Ignition Coil

 As engine technology evolves, coil-on-plug technology will continue to play an increasingly important part of ignition systems. This product category will be at the forefront for years to come, and Intermotor® is leading the way with an expansive selection of quality ignition components.

Designed To Take The Heat

Intermotor® Coil-on-Plug Assembly

The ignition coil converts a low voltage current to high voltage energy that is delivered to the spark plug to ignite the air/fuel mixture within the cylinder. A coil-on-plug is designed to perform the functions of both the ignition coil which creates the spark energy, and the spark plug wire set that is designed to contain and deliver the high voltage energy to the spark plug. Intermotor® Coil-on-Plug assemblies are engineered and tested to meet or exceed OE standards for spark energy, impedance, and durability.

Manufactured in SMP’s TS16949 certified, Bialystok, Poland facility, our specially formulated epoxy is high temperature shock-resistant to handle rapid changes in engine temperature and prevent cracking or coil damage. Engineered to bond with the coil housing and bobbins, our unique process eliminates air pockets and prevents moisture intrusion and thermal breakdown. It’s just one more design detail that makes us the import leader by design.

Ignition Coil

Tin-plated brass terminals for corrosion protection and improved electrical contact

Samarium-cobalt magnet in the core creates a strong magnetic field for maximum high voltage output at all speeds

Improved secondary windings using ETP copper wire provides maximum voltage conductivity

High-temp silicone boot stays flexible for easy removal during related component servicing

Stainless Steel Spring to resist corrosion

Reinforced bobbins and additional winding bays prevent internal arcing, high voltage breakdown, and voltage flashover

Exact-match electronic module feedback signal

Primary coil winding made of 200°C/392°F insulated premium 25-gauge copper wire - engineered and precision wound to generate a strong magnetic field for improved performance

Secondary coil windings are precision wound and trimmed to produce desired output voltage

Bobbin is made from polyphenylene oxide glass material to prevent voltage leaking between the primary and secondary coils

Housing constructed from high dielectric and impact resistant material that ensures long life in operating conditions


Pencil Coils

As engine technology evolves, coil-on-plug technology will continue to play an increasingly important part of ignition systems. One such technology is the pencil coil. Intermotor® is leading the way with quality parts and exceptional coverage for this growing category.

Pencil Coil

Tech Tip: If there’s been a failure such as a short, we recommend replacing the spark plug while you’re replacing the pencil coil.

Electronic ignition module profile and feedback signal matches fit, form, and function of original

Neodymium magnet produces max high voltage output at all speeds

Internal core made from grainoriented electrical steel limits loss factor within magnetic circuit to reduce heat that may affect coil endurance

Stainless steel spring resists corrosion

Tin-plated brass terminals improve electrical contact and protect against corrosion

Elite Manufacturing and Testing

Intermotor® engineers and manufactures high-quality ignition coils and ignition components at our 60,000 sq. ft. facility in Bialystok, Poland.

Highlights of the TS16949-certified facility include lean manufacturing methods and vertically integrated manufacturing processes that include multi-spindle winding, injection molding, potting, curing, and welding.

To ensure quality, all products manufactured at the facility undergo a full spectrum of measurement and life testing in addition to a full range of environmental analysis that includes thermal shock, thermal cycling, salt spray, vibration, and storage tests.


Ignition Modules

Intermotor® Ignition Modules use top of the line technology to ensure perfect timing every time. We match the OE part and ensure better connections, greater dependability, and longer life despite being subjected to intense vibrations and the tough operating environment of the engine.
