HG-Motorsport High Performance ignition coils

Technical optimisation for maximum power

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

In modern vehicles, particularly on engines with increased power output, original ignition coils quickly reach their limits.

Misfires, uneven combustion and thermal overload are often the result.

HG-Motorsport High Performance ignition coils have been developed specifically to overcome these challenges.

They offer increased ignition energy and higher thermal stability, and deliver consistently reliable performance – even under the harshest conditions.

Technical features of HG-Motorsport ignition coils

• Optimised primary and secondary windings: More windings and high-quality copper wire ensure improved energy transfer and a consistently high ignition voltage.
• Increased ignition energy (+10% compared with OE): Perfect spark plug supply throughout the entire dwell period, ideal for high-output engines.
• Constant energy output under high load: Particularly suitable for turbocharged and supercharged engines that need a stable ignition voltage over longer periods.
• Longer service life: High-quality insulation materials and optimised windings minimise thermal stress and protect against internal short circuits.
• Thermal resistance: Continuous use up to 120 °C and stable operation up to 140 °C without loss of performance.
• Optimised spark formation: Stable ignition even at high boost pressures and richer mixtures, which noticeably improves combustion efficiency.

The diagram shows the superior ignition energy of HG-Motorsport ignition coils compared with standard components:

• Up to 1.5 ms: Both types of coil deliver comparable energy.
• From 2.0 ms: The energy of the standard ignition coils drops significantly, while the HG-Motorsport ignition coils continue to deliver consistently high values.
• At 3.0 ms: The HG-Motorsport ignition coils deliver almost 25 % more energy – crucial 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 OE coils already fail or reach critical values.

Ideal for these applications

• High-performance engines: Optimum ignition even under extreme loads.
• Motorsport & trackdays: Stability and constant energy in continuous operation.
• Daily driver with a power upgrade: Better efficiency and ignition stability in everyday driving.
• As a replacement for OEM 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, a constant ignition energy is maintained even at high revs and peak loads.

Thermal tests and long-term results

1. Continuous thermal load

• Test set-up: Continuous operation at 120 °C with simulated load changes over 100 hours.
• Result: No loss of performance and no thermal degradation of the HG-Motorsport ignition coils.
• Comparison: OE ignition coils lost around 25 % of their energy after 50 hours, followed by the first changes in the material.

Additional test at 140 °C

• HG-Motorsport: Stable operation for over 8 hours without failures.
• OE ignition coils: Drop in performance of up to 40 % after 4 hours, followed by thermal failures.
