The high-voltage interface features silicone-sealing and anti-oxidation coating, Not cracking or softening from -40°C to 150°C. It blocks oil/water ingress, 500-hour vibration/salt-spray tests, with a design lifespan exceeding 90,000 km (actual lifespan varies with usage conditions and maintenance).
UKUN ignition coils use high-temperature/corrosion-resistant epoxy resin. Their internally multi-layer precision-wound high-purity copper wires and high-conductivity cores enable efficient energy conversion (60-100mJ ignition energy),and paired with double iridium spark plugs,they achieve full fuel combustion.
