HG Motorsport ignition coils for Mercedes C/CLS/E/GLC/GLE/M 3.0–3.5L, C43 AMG

Technical optimisation for maximum power

HG Motorsport high-performance ignition coils

Maximum ignition energy and high thermal stability for modern high-performance engines. In modern vehicles, particularly tuned engines, 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 specifically developed to overcome these challenges. They provide increased ignition energy, enhanced thermal stability and consistently reliable performance, even under the most demanding conditions.

Technical features of the HG Motorsport ignition coils

• Optimised primary and secondary windings: more windings and high-quality copper wire provide improved energy transfer and consistently high ignition voltage.
• Increased ignition energy (+10% compared with OE): perfect spark plug supply throughout the entire dwell period, ideal for high-performance engines.
• Consistent energy output under high load: particularly suitable for turbocharged and supercharged engines requiring stable ignition voltage over longer periods.
• Extended service life: high-quality insulation materials and optimised windings minimise thermal loads and protect against internal short circuits.
• Thermal resistance: continuous operation 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, significantly improving combustion efficiency.

Ignition energy comparison

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

• Up to 1.5 ms: both coil types 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, which is crucial at high engine speeds and in tuned engines.

Even at a temperature of 140°C, the ignition energy of the HG Motorsport ignition coils remains stable at 70 mJ, while the OE coils are already failing or reaching critical values.

Ideal applications

• High-performance engines: optimum ignition even under extreme loads.
• Motorsport and track days: stability and consistent energy during continuous operation.
• Daily drivers with increased power: improved efficiency and ignition stability in everyday use.
• As a replacement for OEM ignition coils: higher reliability and a longer service life.

Winding structure and operation

The ignition coils use an optimised primary and secondary coil structure. The primary winding generates a strong magnetic field which induces high voltage in the secondary winding as the field collapses. The increased number of windings and improved insulation ensure consistent ignition energy, even at high engine speeds and peak loads.

Thermal testing 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 reduction in performance and no thermal degradation of the HG Motorsport ignition coils.
• Comparison: OE ignition coils lost approximately 25% of their energy after 50 hours, followed by initial material changes.

Additional test at 140°C

• HG Motorsport: stable operation for 8 hours without failures.
• OE ignition coils: performance drop of up to 40% after 4 hours, followed by thermal failures.

Summary of laboratory data

• Maximum ignition energy: HG Motorsport 120 mJ; OE ignition coil 90 mJ.
• Continuous operation at 120°C: HG Motorsport > 100 hours; OE 50 hours.
• Functionality at 140°C: HG Motorsport stable for up to 8 hours; OE performance loss after 4 hours.
• Insulation resistance (500 V): HG Motorsport > 20 MΩ; OE approximately 10 MΩ.
