In tuned engines, original ignition coils quickly reach their limits, often resulting in misfires, uneven combustion and thermal overload. HG Motorsport coils have been specifically developed to overcome these issues, delivering consistently reliable performance even under the most demanding conditions.<\/p>\n<h3>Technical features<\/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 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 that require 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 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 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 the standard ignition coils drops significantly, while the HG Motorsport coils maintain consistently high values.<\/li>\n<li>At 3.0 ms, the HG Motorsport coils deliver almost 25% more energy, which is crucial at high engine speeds and in tuned engines.<\/li>\n<li>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.<\/li>\n<\/ul>\n<h3>Ideal areas of application<\/h3>\n<ul>\n<li>High-performance engines: optimum ignition even under extreme loads.<\/li>\n<li>Motorsport and track days: stability and consistent energy during continuous operation.<\/li>\n<li>Daily drivers with increased power: improved efficiency and ignition stability in everyday use.<\/li>\n<li>Replacement for OEM ignition coils: 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 winding structure. The primary winding generates a strong magnetic field; as this field collapses, a 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 during load peaks.<\/p>\n<h3>Thermal testing and long-term results<\/h3>\n<ol>\n<li><strong>Continuous thermal load:<\/strong> the test was carried out at 120\u00b0C with simulated load changes over more than 100 hours. The HG Motorsport coils showed no reduction in performance or thermal degradation. OE ignition coils lost approximately 25% of their energy after 50 hours, followed by initial material changes.<\/li>\n<li><strong>Additional test at 140\u00b0C:<\/strong> HG Motorsport coils operated stably for 8 hours without failures. OE ignition coils suffered a performance drop of up to 40% after 4 hours, followed by thermal failures.<\/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 50 hours.<\/li>\n<li><strong>Functionality at 140\u00b0C:<\/strong> HG Motorsport stable for up to 8 hours; OE performance drop after 4 hours.<\/li>\n<li><strong>Insulation resistance (500 V):<\/strong> HG Motorsport > 20 M\u03a9; OE approximately 10 M\u03a9.<\/li>\n<\/ul>\n<h3>Replaces the following OEM numbers<\/h3>\n<p>04C905110A, 04C905110B, 04C905110D, 04C905110E, 04C905110H, 04C905110J, 04C905110K, 04C905110L, 04E905110, 04E905110A, 04E905110B, 04E905110C, 04E905110C, 04E905110D, 04E905110E, 04E905110F, 04E905110G, 04E905110H, 04E905110K, 04E905110L, 04E905110M, 04E905110N, 04E905110P<\/p>\n<p><strong>Suitable for:<\/strong> Audi A1 I (8X) \/ II (GB), Audi A3 II (8P) \/ III (8V) \/ IV (GY), Audi A4 IV (B9), Audi Q2 I (GA), Audi Q3 I (8U), SEAT Altea I (5P1), SEAT Arona I (KJ7), SEAT Ateca I (KH7), SEAT Ibiza IV (6J\/6P) \/ V (KJ1), SEAT Leon II (1P1) \/ III (5F), SEAT Toledo III (5P2) \/ IV (KG3), \u0160koda Fabia II (5J) \/ III (NJ3) \/ IV (PJ3), \u0160koda Kamiq I (NW4), \u0160koda Octavia II (1Z3) \/ III (5E3) \/ IV (NX3) and 18 more.<\/p>\n<h3>Manufacturer\u2019s vehicle data<\/h3>\n<ul>\n<li>HG Hochleistungs Z\u00fcndspule Z\u00fcndspule 1.0, 1.2 ,1.4 TFSI<\/li>\n<\/ul>\n<p><em>Original product name by HG Motorsport (\u00bbz.B.\u00ab = e.g.).
