In modern vehicles, particularly those with tuned engines, original ignition coils quickly reach their limits. Misfires, uneven combustion and thermal overload are common consequences. HG Motorsport high-performance ignition coils have been specifically developed to overcome these challenges. They provide increased ignition energy, improved 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> perfect spark plug supply throughout the entire 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 longer 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 load capacity:<\/strong> continuous use up to 120\u00b0C and stable operation up to 140\u00b0C without loss of performance.<\/li>\n<li><strong>Optimised spark formation:<\/strong> stable ignition even at high boost pressures and 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 ignition coils continue to deliver consistently high values.<\/li>\n<li>At 3.0 ms, the HG Motorsport ignition coils deliver nearly 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 ignition coils remains stable at 70 mJ, while OE coils have already failed or reached 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 trackdays:<\/strong> stability and consistent energy during continuous operation.<\/li>\n<li><strong>Daily drivers with increased performance:<\/strong> improved efficiency and ignition stability in everyday use.<\/li>\n<li><strong>As a replacement for OEM ignition coils:<\/strong> greater reliability and extended service life.<\/li>\n<\/ul>\n<h3>Winding structure and operation<\/h3>\n<p>The ignition coils use an optimised primary and secondary coil structure. The primary winding generates a strong magnetic field; when this field collapses, high voltage is induced in the secondary winding. The increased number of windings and improved insulation ensure consistent ignition energy even at high engine speeds and peak loads.<\/p>\n<h3>Thermal testing and long-term results<\/h3>\n<h4>1.
