Each ignition coil generates secondary voltages exceeding 40,000 volts, which supports firing across 1.2mm+ spark plug gaps even under high cylinder pressure conditions. Modern engine management systems can apply multi-spark strategies during crank/start phases and lean-burn cruise modes with this coil, which supports fuel atomization and reduced hydrocarbon emissions. Each unit undergoes high-voltage bench testing before leaving the production line.
Both primary and secondary copper windings are vacuum-impregnated with thermoset epoxy resin that fills all internal voids. This encapsulation reduces the risk of internal arcing from humidity condensation, suppresses coil whine and vibration buzzing, and provides mechanical protection against engine shake and thermal cycling stress.
This ignition coil replicates OEM electrical characteristics, including primary inductance, turns ratio, and polarity orientation, as well as physical mounting dimensions. Installation follows a simple remove-and-replace procedure. The engine control module automatically adapts to normal manufacturing tolerance variations between coils, so no security coding or parameter reset is required after installation.
Replacing faulty coils with this component addresses intermittent cylinder misfire associated with P0301-P0306 diagnostic trouble codes, resolves hard-starting or no-start conditions caused by weak spark output, restores fuel economy reduced by incomplete combustion, and prevents unburnt fuel discharge that can damage catalytic converters from prolonged misfiring.
Root causes include internal coil winding insulation breakdown from heat and vibration, cracked coil housing that allows moisture ingress, high-voltage spark leakage through damaged coil boots, and carbon tracking on spark plug terminals from poor connection. Diagnosis includes scanning for specific cylinder misfire codes, swapping suspect coils with functional units to track misfire movement, observing flashing check engine lights under acceleration, and noting rough idle with power loss. Solutions include replacing the faulty ignition coil with the 27301-3C000 assembly, replacing all spark plugs if near their service interval, applying dielectric grease inside the coil boot to improve connection and moisture resistance, clearing DTC codes, and conducting a road test to confirm repair.
This condition typically stems from coil insulation breakdown that only occurs under high cylinder pressure, internal high-voltage leakage at operating temperature, and loose or corroded coil connector pins. It presents as misfire only during hard acceleration or uphill driving, with no symptoms at idle or light throttle, making workshop reproduction difficult. Solutions include replacing all ignition coils as a set for vehicles with over 120,000 km of mileage, inspecting and cleaning coil wiring harness connectors, and applying contact cleaner and dielectric grease to all electrical connections.
Root causes include complete coil primary circuit failure, simultaneous failure of multiple coils, and a blown ignition coil fuse. Diagnosis involves observing engine cranking without ignition, confirming no spark at affected cylinders with a spark tester, and detecting multiple cylinder misfire codes stored in the ECU. Solutions include checking the ignition coil fuse and relay first, replacing all failed coils with 27301-3C000 assemblies, and inspecting the crankshaft position sensor signal, which is required for accurate coil firing timing.
This is an aftermarket replacement part manufactured to meet or exceed OEM specifications. It delivers equivalent fit, form, and function compared to the genuine part, at a more competitive price point.
This part fits a range of Hyundai and Kia vehicles with Lambda II 3.3L/3.8L V6 engines from 2010 to 2019. For vehicles not listed in the application section, contact customer support with your VIN number for fit verification.
Standard automotive hand tools are sufficient for most installations. A torque wrench is recommended to ensure all fasteners are tightened to factory specifications. Refer to the professional service manual for your specific vehicle model for detailed instructions.
Warranty coverage follows the official warranty policy. It applies to manufacturing defects under normal use conditions. Improper installation, racing use, or modifications will void the warranty.
Replacing related wear items at the same time (such as full sets of coils, spark plugs, and connector seals) is recommended to support consistent engine operation and reduce repeated labor costs.
Cross-reference the OEM part number 27301-3C000 with your vehicle's VIN through an authorized dealer or the online compatibility checker. The OEM part number is the most accurate identifier for correct part matching.
Production runs support a minimum order quantity of 500 units, with consistent quality control across batch production. Two packaging categories are available: genuine (MOBIS) standard packaging, and aftermarket/brand packaging which includes neutral packaging (most widely used) and custom brand packaging. This supply structure supports commercial procurement for ignition specialists, engine rebuilders, and online auto parts retailers serving global markets.
