HG Motorsport HG high-performance ignition coil VAG 1,5 TFSI EA211 (HGHSZS7)

Technical optimisation for maximum power HG-Motorsport High Performance ignition coils Maximum ignition energy and thermal stability for modern high-performance engines In modern vehicles, especially with tuned engines, original ignition coils quickly reach their limits. Misfires, uneven combustion and thermal overload are frequently the result. The HG-Motorsport High Performance ignition coils have been specially developed to master these challenges. They offer increased ignition energy and greater thermal stability, and ensure consistently reliable performance - even under the toughest conditions. Technical features of the HG-Motorsport ignition coils Optimised primary and secondary windings: more windings and high-quality copper wire ensure improved energy transfer and consistently high ignition voltage. Increased ignition energy (+10 % compared with OE): perfect spark plug supply over the entire dwell period, ideal for powerful engines. Constant energy output under high load: particularly suitable for turbocharged and supercharged engines that need a stable ignition voltage over longer periods. Extended service life: high-quality insulation materials and optimised windings minimise thermal stresses and protect against internal short circuits. Thermal resistance: continuous operation up to 120°C and stable operation up to 140°C without loss of performance. Optimised spark formation: stable ignition even at high boost pressures and with richer mixtures, which significantly improves combustion efficiency. The diagram shows the superior ignition energy of the HG-Motorsport ignition coils compared with standard components: Up to 1.5 ms: both coil types deliver comparable energy. From 2.0 ms: the energy of the standard ignition coils drops significantly, while the HG-Motorsport ignition coils deliver consistently high values. At 3.0 ms: the HG-Motorsport ignition coils deliver almost 25 % more energy - crucial at high revs and on tuned engines. Even at a temperature of 140°C, the ignition energy of the HG-Motorsport ignition coils remains stable (70 mJ), while the OE coils are already failing or reaching critical values. Ideal for these applications: High-performance engines: optimum ignition even under extreme loads Motorsport & track days: stability and constant energy in continuous operation Tuned daily drivers: better efficiency and ignition stability in everyday use As a replacement for OEM ignition coils: greater reliability and longer service life Winding structure and operating principle The ignition coils work with an optimised primary and secondary coil structure. The primary winding generates a strong magnetic field which, when it collapses, induces a high voltage in the secondary winding. Thanks to the higher number of windings and improved insulation, constant ignition energy is ensured even at high revs and load peaks. Thermal tests and long-term results 1. Continuous thermal load: Test set-up: continuous operation at 120°C with simulated load changes over 100 hours Result: no reduction in performance and no thermal degradation of the HG-Motorsport ignition coils Comparison: OE ignition coils lost approx. 25 % of their energy after 50 hours, followed by the first changes in the material Additional test at 140°C: HG-Motorsport: stable operation over 8 hours without failures OE ignition coils: drop in performance of up to 40 % after 4 hours, followed by thermal failures Summary of the laboratory data: Parameter HG-Motorsport OE ignition coil Maximum ignition energy (mJ) 120 90 Continuous load at 120°C (hours) > 100 50 Functionality at 140°C Stable up to 8 hours Drop in performance after 4 h Insulation resistance (500 V) > 20 MΩ approx. 10 MΩ Order now and experience noticeably more power!
