Technical Specifications

Vehicle Compatibility Highlights

The NGK 6345 is engineered to fit a wide array of engines. Below are representative vehicle families and engine types where this spark plug is commonly used:

• CITROËN: Various inline‑4 gasoline engines, including those in the C3 and C4 series.
• PEUGEOT: Engines found in the 205, 306, 406, 807, and 908 models; also compatible with newer 1.6L and 2.0L units.
• RENAULT: Suitable for engines in the Megane I, Megane Scenic, Clio, and other compact cars.
• SKODA: Fits 1.4L, 1.5L, and 2.0L gasoline units used in the Octavia, Fabia, and Rapid.

Installation Guide

1. Prepare the Engine: Ensure the engine is cool to avoid burns. Disconnect the battery for safety if required by your vehicle’s service manual.
2. Remove Old Plug: Use a spark plug socket and ratchet to unscrew the existing plug, taking care not to damage the cylinder head threads.
3. Inspect the Socket: Clean any debris or corrosion from the socket opening to prevent cross‑contamination.
4. Insert New Plug: Hand‑tighten the NGK 6345 until it is snug. Then use a torque wrench set to the specified value (typically 35 lb‑ft) to achieve proper seating without over‑torquing.
5. Check Spark Gap: Verify that the spark gap matches the manufacturer’s specification using a spark plug gauge. Adjust if necessary before final tightening.
6. Reconnect Battery and Test: Reconnect the battery, start the engine, and listen for smooth operation. A consistent spark should indicate correct installation.

Performance Benefits

• Enhanced Combustion Efficiency: The precise electrode geometry promotes a clean, high‑energy spark that ignites fuel more completely, improving power output.
• Reduced Fuel Consumption: Efficient combustion translates to lower fuel usage, offering cost savings over the life of the plug.
• Lower Emissions: Complete ignition reduces unburnt hydrocarbons, helping vehicles meet stringent emission standards.
• Longer Service Life: Platinum electrodes resist wear, allowing plugs to maintain performance for up to 100,000 miles in many applications.

Maintenance Tips

• Regular Inspection: Check spark plug condition during routine maintenance intervals. Look for signs of fouling or excessive wear.
• Clean the Socket: Keep the spark plug socket free from oil, dirt, and corrosion to ensure accurate torque application.
• Use Proper Tools: Employ a calibrated torque wrench; over‑tightening can damage threads while under‑tightening may lead to poor contact.
