Misfires, uneven combustion and thermal overload can 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 improve energy transfer and provide a 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 output under high load:<\/strong> particularly suitable for turbocharged and supercharged engines requiring a stable ignition voltage over longer periods.<\/li>\n<li><strong>Extended service life:<\/strong> high-quality insulation materials and optimised windings minimise thermal stress 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 even at high boost pressure 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 the standard ignition coils drops noticeably, 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 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 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> 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; when this field collapses, it induces a high voltage 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<h4>1. Continuous thermal load<\/h4>\n<ul>\n<li><strong>Test setup:<\/strong> continuous operation at 120\u00b0C with simulated load changes over 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<h4>Additional test at 140\u00b0C<\/h4>\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<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>Operating capability 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 approx. 10 M\u03a9.<\/li>\n<\/ul>\n<h3>Compatible original part numbers<\/h3>\n<p>This conversion kit can replace the following OEM numbers: 06A905115, 06A905115A, 06A905115B, 06A905115C, 06A905115D, 06B905115D, 06B905115G, 06B905115H, 06B905115J, 06B905115L, 06B905115M, 06B905115N, 06B905115P, 06B905115R, 06B905115S, 06B905115T, 06B905116J, 06B905117L, 06C905115C, 058905101, 058905105, 06B905105, 06B905115, 06B905115B, 06B905115E.<\/p>\n<p><strong>Suitable for:<\/strong> Audi A3 I (8L), Audi A4 I (B5) \/ II (B6\/B7), Audi A6 II (C5) \/ III (C5\/4B), Audi TT I (8N), SEAT Alhambra I (7MS) \/ I (7V8\/7V9), SEAT Ibiza II (6K1) \/ III (6L1), SEAT Leon I (1M1), SEAT Toledo II (1M2), \u0160koda Octavia I (1U2) \/ I (1U5), \u0160koda Superb I (3U4), VW Beetle I (9C), VW Bora I (1J), VW Golf IV (1J), VW New Beetle I (1Y7) and 3 more.<\/p>\n<h3>Manufacturer\u2019s vehicle data<\/h3>\n<ul>\n<li>HG Motorsport Hochleistungs Z\u00fcndspulen Umbausatz VAG 1,8T 20V<\/li>\n<\/ul>\n<p><em>Original product name by HG Motorsport (\u00bbz.B.\u00ab = e.g.).
