Misfires, uneven combustion and thermal overload can be the result. HG Motorsport high-performance ignition coils have been specially developed to overcome these challenges. They provide increased ignition energy, enhanced thermal stability and consistently reliable performance, even under the most demanding conditions.<\/p>\n<h3>Technical features of the HG Motorsport ignition coils<\/h3>\n<ul>\n<li><strong>Optimised primary and secondary windings:<\/strong> additional windings and high-quality copper wire provide improved energy transfer and consistently high ignition voltage.<\/li>\n<li><strong>Increased ignition energy (+10% compared with OE):<\/strong> optimum spark plug supply throughout the complete dwell period, ideal for high-performance engines.<\/li>\n<li><strong>Consistent energy delivery under high load:<\/strong> particularly suitable for turbocharged and supercharged engines requiring stable ignition voltage over extended periods.<\/li>\n<li><strong>Extended service life:<\/strong> high-quality insulation materials and optimised windings minimise thermal loads and protect against internal short circuits.<\/li>\n<li><strong>Thermal resistance:<\/strong> continuous operation up to 120\u00b0C and stable operation up to 140\u00b0C without loss of performance.<\/li>\n<li><strong>Optimised spark generation:<\/strong> stable ignition even at high boost pressures and with richer mixtures, significantly improving combustion efficiency.<\/li>\n<\/ul>\n<h3>Ignition energy comparison<\/h3>\n<p>The diagram shows the superior ignition energy of the HG Motorsport ignition coils compared with standard components:<\/p>\n<ul>\n<li>Up to 1.5 ms: both coil types deliver comparable energy.<\/li>\n<li>From 2.0 ms: the energy of standard ignition coils drops significantly, while the HG Motorsport coils continue to deliver consistently high values.<\/li>\n<li>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.<\/li>\n<\/ul>\n<p>Even at a temperature of 140\u00b0C, the ignition energy of the HG Motorsport coils remains stable at 70 mJ, while OE coils are already failing or reaching critical values.<\/p>\n<h3>Ideal applications<\/h3>\n<ul>\n<li><strong>High-performance engines:<\/strong> optimum ignition even under extreme loads.<\/li>\n<li><strong>Motorsport and track days:<\/strong> stability and consistent energy during continuous operation.<\/li>\n<li><strong>Daily drivers with increased power:<\/strong> improved efficiency and ignition stability in everyday use.<\/li>\n<li><strong>Replacement for OE ignition coils:<\/strong> greater reliability and a longer service life.<\/li>\n<\/ul>\n<h3>Winding structure and operation<\/h3>\n<p>The ignition coils use an optimised primary and secondary winding structure. The primary winding creates a strong magnetic field which induces a high voltage in the secondary winding as the field collapses. Thanks to the increased number of windings and improved insulation, consistent ignition energy is maintained even at high engine speeds and during peak loads.<\/p>\n<h3>Thermal testing and long-term results<\/h3>\n<p><strong>1.
