HG-Motorsport High Performance Ignition Coils

Technical Optimization for Maximum Power

Modern high-performance engines require ignition systems that can handle extreme conditions. Stock ignition coils often reach their limits, leading to misfires, uneven combustion, and thermal overload.

The HG-Motorsport High Performance Ignition Coils are engineered to overcome these challenges, providing:

• Increased ignition energy
• Enhanced thermal stability
• Reliable performance under extreme conditions

Technical Features of HG-Motorsport Ignition Coils

• Optimized primary and secondary windings: More windings and high-quality copper wire ensure improved energy transfer and consistently high ignition voltage.
• Increased ignition energy (+10% vs. OE): Provides optimal spark plug supply throughout the entire dwell time, ideal for high-performance engines.
• Stable energy output under high loads: Particularly suitable for turbocharged and supercharged engines that require a steady ignition voltage over extended periods.
• Extended lifespan: Premium insulation materials and optimized winding structures reduce thermal stress and prevent internal short circuits.
• Thermal endurance: Continuous operation up to 120°C and stable performance up to 140°C without power loss.
• Optimized spark formation: Ensures stable ignition even at high boost pressures and richer fuel mixtures, significantly improving combustion efficiency.

Superior Ignition Energy – Performance Comparison

The diagram illustrates the superior ignition energy of HG-Motorsport Ignition Coils compared to stock components:

• Up to 1.5 ms: Both coil types deliver comparable energy.
• At 2.0 ms: Stock coil energy starts dropping significantly, while HG-Motorsport coils maintain high levels.
• At 3.0 ms: HG-Motorsport coils provide nearly 25% more energy, crucial for high-revving and tuned engines.
• Even at 140°C, HG-Motorsport coils maintain stable ignition energy (70 mJ), while OE coils show critical energy loss or failure.

Ideal Applications:

✔ High-performance engines: Ensuring optimal ignition even under extreme conditions.
✔ Motorsport & Track Days: Stability and constant energy output during continuous operation.
✔ Daily drivers with performance upgrades: Better efficiency and ignition stability in everyday use.
✔ OEM coil replacement: Increased reliability and longer lifespan compared to factory coils.

Advanced Winding Structure & Function

The ignition coils operate with an optimized primary and secondary winding structure.

• The primary winding generates a strong magnetic field, which induces a high voltage in the secondary winding when it collapses.
• Higher winding count and improved insulation ensure consistent ignition energy, even at high RPM and peak loads.

Thermal & Long-Term Testing

1. Thermal Stress Test

• Test conditions: 100+ hours of continuous operation at 120°C with simulated load changes.
• Results:
  • HG-Motorsport Coils: No performance loss, no thermal degradation.
  • OE Coils: Lost 25% of energy after 50 hours, followed by material breakdown.

2. Additional Stress Test at 140°C

• HG-Motorsport: Stable operation for 8 hours without failure.
• OE Coils: Performance drop up to 40% after 4 hours, leading to thermal failure.
