Technical optimisation for maximum performance<\/strong><\/p>\n

HG Motorsport high-performance ignition coils<\/strong><\/p>\n

Maximum spark energy and thermal stability for modern high-performance engines.<\/p>\n

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 have been developed specifically to overcome these challenges. They provide increased spark energy, enhanced thermal stability and consistently reliable performance, even under the most demanding conditions.<\/p>\n

Technical features of the HG Motorsport ignition coils<\/h3>\n
    \n
  • Optimised primary and secondary windings:<\/strong> More turns and high-quality copper wire provide improved energy transfer and consistently high ignition voltage.<\/li>\n
  • Increased spark energy (+10% compared with OE):<\/strong> Perfect spark plug supply throughout the complete dwell period, ideal for high-performance engines.<\/li>\n
  • Consistent energy output under high load:<\/strong> Particularly suitable for turbocharged and supercharged engines that require stable ignition voltage over longer periods.<\/li>\n
  • Extended service life:<\/strong> High-quality insulation materials and optimised windings minimise thermal loads and protect against internal short circuits.<\/li>\n
  • Thermal resistance:<\/strong> Continuous operation up to 120\u00b0C and stable operation up to 140\u00b0C without loss of performance.<\/li>\n
  • Optimised spark formation:<\/strong> Stable ignition even at high boost pressures and richer mixtures, significantly improving combustion efficiency.<\/li>\n<\/ul>\n

    The diagram shows the superior spark energy of the HG Motorsport ignition coils compared with standard components:<\/p>\n

      \n
    • Up to 1.5 ms:<\/strong> Both coil types deliver comparable energy.<\/li>\n
    • From 2.0 ms:<\/strong> The energy of standard ignition coils drops significantly, while the HG Motorsport ignition coils continue to deliver consistently high values.<\/li>\n
    • At 3.0 ms:<\/strong> The HG Motorsport ignition coils deliver almost 25% more energy, which is decisive at high engine speeds and in tuned engines.<\/li>\n<\/ul>\n

      Even at a temperature of 140\u00b0C, the spark energy of the HG Motorsport ignition coils remains stable at 70 mJ, while OE coils have already failed or reached critical values.<\/p>\n

      Ideal for the following applications<\/h3>\n
        \n
      • High-performance engines:<\/strong> Optimum ignition even under extreme loads.<\/li>\n
      • Motorsport and track days:<\/strong> Stability and consistent energy during continuous operation.<\/li>\n
      • Daily drivers with increased performance:<\/strong> Improved efficiency and ignition stability in everyday use.<\/li>\n
      • As a replacement for OEM ignition coils:<\/strong> Greater reliability and a longer service life.<\/li>\n<\/ul>\n

        Winding structure and operation<\/h3>\n

        The ignition coils use an optimised primary and secondary coil structure. The primary winding generates a strong magnetic field; when this field collapses, a high voltage is induced in the secondary winding. The increased number of turns and improved insulation ensure consistent spark energy even at high engine speeds and peak loads.<\/p>\n

        Thermal tests and long-term results<\/h3>\n
          \n
        1. Continuous thermal load:<\/strong> Test setup: continuous operation at 120\u00b0C 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.<\/li>\n
        2. Additional test at 140\u00b0C:<\/strong> HG Motorsport: stable operation for 8 hours without failures.
          OE ignition coils: performance loss of up to 40% after 4 hours, followed by thermal failures.<\/li>\n<\/ol>\n

          Summary of laboratory data<\/h3>\n
            \n
          • Maximum spark energy:<\/strong> HG Motorsport 120 mJ; standard ignition coil 90 mJ.<\/li>\n
          • Continuous load at 120\u00b0C:<\/strong> HG Motorsport > 100 hours; standard ignition coil 50 hours.<\/li>\n
          • Functionality at 140\u00b0C:<\/strong> HG Motorsport stable for up to 8 hours; standard ignition coil performance loss after 4 hours.<\/li>\n
          • Insulation resistance (500 V):<\/strong> HG Motorsport > 20 M\u03a9; standard ignition coil approximately 10 M\u03a9.<\/li>\n<\/ul>\n
