HG Motorsport ignition coils for Ford 1.5T EcoBoost (Focus, Fiesta, Kuga, Puma)

Technical optimisation for maximum power

HG Motorsport High Performance ignition coils

Maximum spark energy and thermal stability for modern high-performance engines. In modern vehicles, particularly those with uprated engines, original ignition coils quickly reach their limits. Misfires, uneven combustion and thermal overload are common results. HG Motorsport High Performance ignition coils have been developed specifically to overcome these challenges. They provide increased spark 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 turns and high-quality copper wire provide improved energy transfer and consistently high ignition voltage.
• Increased spark energy (+10% compared with OE): perfect spark plug supply throughout the complete dwell period, ideal for high-performance engines.
• Constant energy delivery under high load: particularly suitable for turbocharged and supercharged engines that require stable ignition voltage for 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 with richer mixtures, significantly improving combustion efficiency.

Spark energy comparison

The diagram shows the superior spark 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 decisive at high engine speeds and in uprated engines.

Even at a temperature of 140°C, the spark energy of the HG Motorsport ignition coils remains stable at 70 mJ, while OE coils have already failed or reached critical values.

Ideal for the following 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: greater 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 it collapses. Thanks to the increased number of turns and improved insulation, consistent spark energy is maintained even at high engine speeds and during load peaks.

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 the first material changes.
2. Additional test at 140°C: HG Motorsport coils operated steadily for 8 hours without failures. OE ignition coils suffered a performance loss of up to 40% after 4 hours, followed by thermal failures.

Summary of laboratory data

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

HG Motorsport High Performance ignition coils provide the stability, maximum spark energy and extended service life required by high-performance engines. The coil replaces, for example, the following OEM part numbers: HX7G12A366AA, HX7G12A366AB, 19050114, 2249266, 2311876.

Suitable for: Ford Fiesta VII (JHH) / VII (JV) / VIII (MK8), Ford Focus III (DYB) / IV (DEH), Ford Kuga II (DM2) / III (DFK), Ford Puma II (J2K).
