HG Motorsport ignition coils for VAG 1.4 TFSI

Technical optimisation for maximum power

HG Motorsport high-performance ignition coils provide increased ignition energy and improved 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 can result. HG Motorsport high-performance ignition coils were developed specifically to overcome these challenges. They provide increased ignition energy, improved 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): optimum spark plug supply throughout the complete dwell period, ideal for high-performance engines.
• Consistent energy output under high load: particularly suitable for turbocharged and supercharged engines that require stable ignition voltage over longer periods.
• Extended service life: high-quality insulating materials and optimised windings minimise thermal loads 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 at high boost pressures and richer mixtures, significantly improving combustion efficiency.

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 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 decisive 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 OE coils are already failing or reaching critical values.

Ideal applications

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

Winding structure and operation

The ignition coils use an optimised primary and secondary winding 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 setup: continuous operation at 120°C with simulated load changes for more than 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.
2. Additional test at 140°C
   HG Motorsport: stable operation for more than 8 hours without failures.
   OE ignition coils: performance loss 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 load at 120°C: HG Motorsport > 100 hours; OE 50 hours.
• Functionality at 140°C: HG Motorsport stable for up to 8 hours; OE performance drop after 4 hours.
• Insulation resistance (500 V): HG Motorsport > 20 MΩ; OE approximately 10 MΩ.
