Structural Design
Electromagnetic Core Assembly
The operational heart of the coil features a high-permeability silicon steel core enveloped by precision-wound primary and secondary copper coils. This configuration maximizes magnetic flux for rapid and efficient voltage multiplication.
01
Low-Voltage Interface
Equipped with a side-mounted 4PIN waterproof connector featuring gold-plated terminals and secure locking tabs, it ensures an uninterrupted electrical link to the engine harness, resisting disconnection from severe engine vibrations.
02
High-Voltage Output Terminal
The top-mounted ceramic tower, protected by a heat-resistant silicone boot, provides a direct and insulated pathway to the spark plug. Its superior dielectric properties prevent voltage bleed-off and ensure the spark reaches the electrode precisely.
03
Precision Mounting Bracket
The integrated metal-plastic bracket is CNC-machined to align perfectly with the cylinder head. A specialized anti-vibration rubber gasket absorbs mechanical shocks, protecting the delicate internal windings from structural fatigue.
04
Hermetically Sealed Enclosure
The monolithic PBT housing, combined with vacuum epoxy encapsulation, creates an impenetrable barrier. This design isolates the electromagnetic assembly from harsh engine fluids and extreme thermal cycling, drastically extending service life.

Installation Guidelines
Safety Preparation: Always disconnect the negative battery terminal before beginning installation. Wait 3-5 minutes to allow residual electrical charge in the ignition system to dissipate, preventing short circuits or damage to sensitive electronic components.
Temperature Precautions: Ensure the engine has cooled to below 40℃ before handling. Installing the coil on a hot engine can cause burns and may lead to thermal deformation of the plastic housing or rubber seals.
Surface Preparation: Clean the cylinder head mounting surface and spark plug well thoroughly. Remove any oil, carbon deposits, or debris to ensure a proper seal between the coil and spark plug, preventing spark leakage or poor electrical contact.
Proper Installation: Align the coil vertically with the spark plug and mounting hole. Press down firmly until the mounting bracket sits flush against the cylinder head, then secure with the mounting bolt to the specified torque of 9.5-11.5 N·m to prevent loosening from engine vibration.
Post-Installation Verification: Reconnect the battery and start the engine. Check for smooth idling, absence of misfires, and no illuminated check engine lights. Conduct a test drive at various speeds to confirm proper operation.
Set Replacement Recommendation: If multiple cylinders are experiencing ignition issues, consider replacing all coils as a set. This ensures uniform spark performance across all cylinders, prevents uneven power delivery, and extends the life of associated ignition components.
Packaging, Storage & Logistics
The Ignition Coil OE:06E905115D is individually packed in anti-static sealed bags, cushioned with EPE foam inside sturdy corrugated cartons to prevent damage during transit. Outer cartons are clearly labeled with product details, weight, and handling symbols (anti-shock, moisture-proof, fragile) for easy identification and management.
Storage Conditions: Keep in original packaging in a clean, dry, well-ventilated warehouse at -5℃ to 45℃ with relative humidity ≤70%. Protect from direct sunlight, extreme heat, moisture, oil, and strong electromagnetic fields. Shelf life is 36 months under proper conditions.
Handling Instructions: Handle with care. Avoid dropping, crushing, or applying excessive force. Do not pull on the electrical connector or high-voltage tower, as this can damage internal wiring, insulation, or terminal pins.
Transportation: Suitable for road, sea, or air freight. Ensure packaging remains intact and protected from rain, snow, extreme heat, and direct sunlight during transit. Secure cartons properly in the transport vehicle to prevent shifting, collision, or stacking damage
