NGK 48312 Ignition Coil

NGK 48312 Ignition Coil

The NGK 48312 Ignition Coil is a high‑performance component engineered to deliver reliable spark generation for a wide range of small engines, particularly those found in LADA, CHEVROLET Niva, MITSUBISHI LADA, and DATSUN models. Designed with precision engineering, this coil ensures optimal ignition timing, improved fuel efficiency, and reduced emissions.

Key Features

• Compact Design: The coil’s small footprint allows it to fit seamlessly into tight engine bays without compromising airflow or cooling.
• High Voltage Output: Generates up to 45,000 volts, providing a strong spark that penetrates even the most demanding combustion chambers.
• Durable Construction: Made from high‑grade copper windings and reinforced ceramic insulation, it withstands extreme temperatures and vibration.
• Low Resistance: A resistance of approximately 0.5 ohms ensures efficient energy transfer and minimal power loss.
• Wide Compatibility: Matches the specifications for models such as LADA Niva (2121, 2131), CHEVROLET Niva, MITSUBISHI LADA, DATSUN Mi‑Do, On‑Do, and various LADA 110/111/112 Granta Kalina variants.

Technical Specifications

Installation Guide

1. Preparation: Disconnect the battery and remove any existing ignition coil. Ensure the engine is cool to avoid burns.
2. Positioning: Align the M4 threaded socket with the engine’s mounting point. The coil should sit flush against the cylinder head for optimal heat dissipation.
3. Screwing In: Tighten the M4 nut to the manufacturer’s torque specification (typically 15–20 Nm). Use a calibrated torque wrench for accuracy.
4. Wiring: Connect the positive, negative, and ground leads. Verify polarity: the positive lead should connect to the high‑voltage terminal on the spark plug wire.
5. Testing: Reconnect the battery and start the engine. Observe smooth idling and consistent acceleration. If misfires occur, double‑check connections and torque settings.

Performance Benefits

• Enhanced Combustion Efficiency: The high‑voltage spark ensures complete fuel–air mixture ignition, leading to smoother engine operation.
• Reduced Fuel Consumption: Precise timing reduces wasted energy, translating into lower fuel usage over time.
• Lower Emissions: Efficient combustion produces fewer unburnt hydrocarbons and CO₂ emissions.
• Longer Engine Life: Consistent spark delivery minimizes wear on pistons, valves, and other internal components.
