Misfires, uneven combustion and thermal overload can be the result. 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> more 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>Constant energy output under high load:<\/strong> particularly suitable for turbocharged and supercharged engines that require stable ignition voltage over longer periods.<\/li>\n<li><strong>Extended service life:<\/strong> high-quality insulating 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 formation:<\/strong> stable ignition 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><strong>Up to 1.5 ms:<\/strong> both coil types deliver comparable energy.<\/li>\n<li><strong>From 2.0 ms:<\/strong> the energy of the standard ignition coils drops significantly, while the HG Motorsport ignition coils continue to deliver consistently high values.<\/li>\n<li><strong>At 3.0 ms:<\/strong> 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 ignition coils remains stable at 70 mJ, while OE coils have already failed or reached critical values.<\/p>\n<h3>Ideal for the following 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 power:<\/strong> improved efficiency and ignition stability in everyday use.<\/li>\n<li><strong>Replacement for OEM ignition coils:<\/strong> increased 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; as this field collapses, a high voltage is induced in the secondary winding. The higher number of windings and improved insulation ensure consistent ignition energy, even at high engine speeds and during peak loads.<\/p>\n<h3>Thermal testing and long-term results<\/h3>\n<ol>\n<li><strong>Continuous thermal load<\/strong>\n<ul>\n<li><strong>Test set-up:<\/strong> continuous operation at 120\u00b0C with simulated load changes for more than 100 hours.<\/li>\n<li><strong>Result:<\/strong> no reduction in performance and no thermal degradation of the HG Motorsport ignition coils.<\/li>\n<li><strong>Comparison:<\/strong> OE ignition coils lost approximately 25% of their energy after 50 hours, followed by initial material changes.<\/li>\n<\/ul>\n<\/li>\n<li><strong>Additional test at 140\u00b0C<\/strong>\n<ul>\n<li><strong>HG Motorsport:<\/strong> stable operation for 8 hours without failures.<\/li>\n<li><strong>OE ignition coils:<\/strong> performance drop of up to 40% after 4 hours, followed by thermal failures.<\/li>\n<\/ul>\n<\/li>\n<\/ol>\n<h3>Summary of laboratory data<\/h3>\n<ul>\n<li><strong>Maximum ignition energy:<\/strong> HG Motorsport 120 mJ; OE ignition coil 90 mJ.<\/li>\n<li><strong>Continuous load at 120\u00b0C:<\/strong> HG Motorsport > 100 hours; OE ignition coil 50 hours.<\/li>\n<li><strong>Operation at 140\u00b0C:<\/strong> HG Motorsport stable for up to 8 hours; OE ignition coil performance drop after 4 hours.<\/li>\n<li><strong>Insulation resistance (500 V):<\/strong> HG Motorsport > 20 M\u03a9; OE ignition coil approximately 10 M\u03a9.<\/li>\n<\/ul>\n<h3>Replaces the following OEM numbers<\/h3>\n<p>The ignition coil replaces the following OEM numbers: 1700610, 1762724, 1832313, BM5G-12A366-CA, BM5G-12A366-DA, BM5G-12A366-DB, 1700610, 1762724, 1832313, 31339210, 31375550, 31422117.<\/p>\n<p><strong>Suitable for:<\/strong> Ford Fiesta VI (JA8).<\/p>\n<h3>Manufacturer\u2019s vehicle data<\/h3>\n<ul>\n<li>HG Hochleistungs Z\u00fcndspule Ford Fiesta ST1,6<\/li>\n<\/ul>\n<p><em>Original product name by HG Motorsport (\u00bbz.B.\u00ab = e.g.).
