Key Features

Precise OEM Direct Replacement

Engineered to strict original equipment specifications, the Ignition Coil OE:2730123700 is a plug-and-play solution with no wiring modifications, drilling or additional adapters required. It perfectly aligns with factory mounting points and electrical interfaces, eliminating installation errors and ensuring a hassle-free fitting process.

Stable High-Voltage Output

Adopts a high-density enameled copper wire winding and high-permeability silicon steel core, delivering a steady rated output voltage of ≥34,000V. This generates a strong, consistent spark even under extreme operating conditions like low-temperature startup and high-load driving, effectively preventing engine misfiring and incomplete combustion.

Superior Heat & Corrosion Resistance

The outer housing is crafted from high-strength heat-resistant PBT engineering plastic, capable of withstanding continuous high temperatures up to 195℃ in the engine compartment, with excellent anti-aging, oil-resistant and anti-corrosion properties. The internal high-voltage tower features high-purity ceramic insulation, preventing high-voltage leakage and ensuring long-term stable operation.

Full-Sealed Multi-Layer Protection

Utilizes vacuum epoxy resin encapsulation technology for full-sealed insulation, achieving an IP6K9K dustproof and waterproof rating. It effectively isolates internal components from engine oil, coolant, dust and moisture, while built-in overvoltage and overcurrent protection circuits safeguard the vehicle's ECU and ignition module from electrical damage.

IATF16949 Certified Quality

Produced in compliance with the IATF16949 automotive quality management system, every Ignition Coil OE:2730123700 undergoes rigorous testing including high-voltage withstand, insulation resistance, temperature cycling and 58,000+ durability tests, ensuring a 100% factory pass rate and a service life of over 115,000 kilometers.

Structural Composition

Core Electromagnetic Conversion Assembly

The core functional part of the Ignition Coil OE:2730123700, composed of a high-permeability silicon steel sheet iron core and double-layer enameled copper wire primary and secondary windings. This assembly enables efficient low-to-high voltage conversion and stable energy transmission, the fundamental guarantee for generating a reliable ignition spark.

Low-Voltage Electrical Connector

A side-mounted 4PIN integrated waterproof plastic connector with anti-loosening snap fasteners and gold-plated pins. It ensures a secure connection with the vehicle's ignition wiring harness and ECU, preventing poor contact caused by engine high-frequency vibration and electrical corrosion.

High-Voltage Output Tower

A top-mounted ceramic high-voltage tower with a high-temperature resistant rubber sealing ring, directly mated with the spark plug. It features ultra-high insulation and breakdown resistance, ensuring high-voltage electricity is accurately transmitted to the spark plug electrode without leakage.

Integrated Mounting Bracke

A metal-plastic composite mounting bracket with precision threaded holes, perfectly matching the engine cylinder head mounting points. Equipped with an anti-vibration rubber gasket, it reduces the impact of engine vibration on the product's internal structure and avoids component damage.

Full-Sealed Protective Housing

A one-piece molded heat-resistant PBT housing that fully encases the internal electromagnetic assembly, combined with vacuum epoxy resin encapsulation to form a fully sealed structure. It effectively isolates the harsh engine compartment environment and significantly extends the product's service life.|

Installation and Usage Notes

· Before installing the Ignition Coil OE:2730123700, disconnect the vehicle's negative battery terminal and wait 3-5 minutes to discharge residual electricity in the ignition system, avoiding short circuits and damage to sensitive electrical components.
· Ensure the engine is completely cooled (below 40℃) before installation to prevent scalding and avoid thermal deformation of the coil's plastic and rubber parts due to high temperatures.
· Thoroughly clean the engine cylinder head mounting surface and spark plug installation port, removing oil, dust, carbon deposits and other contaminants to ensure a tight seal between the product and spark plug, and prevent spark leakage and poor contact.
· When installing, align the product vertically with the spark plug and mounting hole, press firmly until the mounting bracket is fully attached to the cylinder head, then tighten the mounting bolt to the specified torque (9.5-11.5 N·m) to prevent loosening caused by engine vibration.
· After installation, reconnect the negative battery terminal, start the engine and check for abnormal conditions such as misfiring, idling instability and illuminated ignition system fault lights. Perform a test drive at idle, medium and high speeds to confirm the product operates normally.
· If multiple cylinders experience ignition failures, it is recommended to replace ignition coils as a set to ensure consistent ignition performance across all cylinders, avoid uneven engine power output and extend the service life of spark plugs and other ignition components.
