HG-Motorsport High Performance ignition coils

Maximum ignition energy and thermal stability for modern high-performance engines.

In modern vehicles, especially with performance-tuned engines, standard ignition coils quickly reach their limits. The result can be misfires, uneven combustion and thermal overload.

The HG-Motorsport high-performance ignition coils were developed to withstand these demands reliably. They offer increased ignition energy, high thermal stability and consistently reliable performance, even under demanding conditions.

Technical features of HG-Motorsport ignition coils

• Optimised primary and secondary winding: Additional windings and high-quality copper wire improve energy transfer and enable a consistently high ignition voltage.
• Increased ignition energy: The ignition energy is up to 10 % above the level of comparable OE ignition coils. This supplies the spark plug reliably over the entire dwell period.
• Constant energy output under high load: The ignition coils are particularly suitable for turbo and supercharged engines that require a stable ignition voltage over a longer period.
• Longer service life: High-quality insulation materials and optimised windings reduce thermal stress and protect against internal short circuits.
• High thermal resistance: The ignition coils are designed for continuous use at temperatures up to 120 °C and allow stable operation up to 140 °C.
• Optimised spark formation: Stable ignition at high boost pressures and richer fuel-air mixtures improves combustion efficiency.

Ignition energy comparison

The chart shows the ignition energy of the HG-Motorsport ignition coils compared with standard ignition coils.

• Up to 1.5 ms both types of coil deliver comparable ignition energy.
• From 2.0 ms the energy of the standard ignition coils drops significantly, while the HG-Motorsport ignition coils continue to deliver constant values.
• At 3.0 ms the HG-Motorsport ignition coils deliver almost 25 % more energy. This is a particular advantage at high revs and with performance-tuned engines.

Even at a temperature of 140 °C the ignition energy of the HG-Motorsport ignition coils remains stable at 70 mJ, while comparable OE ignition coils reach critical values or may fail.

Suitable applications

• High-performance engines: Reliable ignition even under high loads.
• Motorsport and trackdays: Constant energy output in continuous operation.
• Performance-tuned road vehicles: Improved ignition stability and efficiency in everyday driving.
• Replacement for standard ignition coils: Higher reliability and a longer service life.

Winding structure and how it works

The ignition coils work with an optimised primary and secondary coil structure. The primary winding generates a strong magnetic field which, when it collapses, induces a high voltage in the secondary winding.

Thanks to the higher number of windings and improved insulation, the ignition energy remains constant even at high revs and short-term load peaks.

Thermal tests and long-term results

Continuous thermal load

• Test set-up: Continuous operation at 120 °C with simulated load changes over a period of 100 hours.
• Result: No reduction in performance and no thermal impairment of the HG-Motorsport ignition coils.
• Comparison: The tested OE ignition coils lost around 25 % of their energy after 50 hours. First changes in the material then appeared.

Additional test at 140 °C

• HG-Motorsport ignition coils: Stable operation for over eight hours without failures.
• OE ignition coils: Drop in performance of up to 40 % after four hours, followed by heat-related failures.

Summary of laboratory data
