NGK Genuine U1076 Ignition Coil Component 48339

The NGK Genuine U1076 Ignition Coil, catalogued as part number 48339, is a high‑performance ignition component designed to deliver reliable spark generation for a wide range of gasoline engines. This coil is engineered with NGK’s proprietary technology, ensuring optimal voltage output, durability, and compatibility across numerous vehicle makes and models.

Key Design Features

• Precision Coil Winding: The U1076 utilizes a tightly wound primary winding that minimizes inductance loss, providing consistent spark energy even under high engine loads.
• High‑Temperature Resistance: Constructed with advanced insulation materials, the coil can withstand operating temperatures up to 200 °C without degradation, extending its service life in demanding environments.
• Compact Footprint: Its streamlined design allows installation in tight engine bay spaces, making it suitable for both modern and classic vehicles where space is at a premium.
• Robust Metal Housing: The metal shell protects the internal components from vibration, moisture, and mechanical shock, ensuring long‑term reliability.

Performance Characteristics

The U1076 delivers a spark voltage of approximately 12 kV to 15 kV, depending on engine speed and load. This high voltage is essential for igniting the air‑fuel mixture in engines ranging from small 1.0‑liter units to larger 2.5‑liter powerplants. The coil’s low internal resistance (0.3 Ω) reduces energy loss, improving combustion efficiency and reducing fuel consumption.

• Saab: 900, 9000 series
• Daimler (Mercedes‑Benz): XJ, S-Class variants
• Other Brands: Lada, MG, Nissan, Toyota Corolla, Subaru Leone, and many more.

Engineers and technicians frequently select the U1076 for its proven track record in both OEM and aftermarket applications. Its universal fitment across multiple platforms reduces inventory complexity and simplifies maintenance procedures.

Installation Guidelines

1. Remove Existing Coil: Disconnect the battery, remove the spark plug wire, and unscrew the old ignition coil from its mounting bracket.
2. Inspect Mounting Surface: Clean any debris or corrosion to ensure a solid mechanical connection.
3. Position the U1076: Align the coil with the mounting holes and secure it using the supplied bolts. Tighten to the manufacturer’s torque specification (typically 12 Nm).
4. Reconnect Spark Plug Wire: Attach the high‑voltage lead to the coil’s terminal, ensuring a firm connection.
5. Verify Functionality: Start the engine and observe for smooth idling and consistent spark. If misfires occur, double‑check alignment and electrical connections.

Maintenance & Troubleshooting

The U1076 is designed to be a low‑maintenance component; however, regular inspection can preempt potential issues:

• Visual Check: Inspect for cracks or discoloration in the insulation. Any visible damage warrants replacement.
• Electrical Test: Use a multimeter to verify continuity between primary and secondary windings. A resistance reading outside the specified range indicates coil failure.
• Spark Quality: Employ a spark tester or observe engine performance for rough idling, hesitation, or loss of power—common symptoms of a failing ignition coil.
