• Gap Size: Adjustable gap of 0.7–1.2 mm, allowing technicians to fine‑tune ignition timing for specific engine tuning requirements.
• Coating: Nickel‑plated outer shell provides corrosion resistance and extends service life under harsh operating conditions.

Performance Benefits

The combination of platinum and copper alloys in the electrode assembly offers several advantages:

• Extended Service Life: Platinum’s high melting point reduces wear, enabling longer intervals between spark plug replacements.
• Consistent Spark Energy: Copper alloy ground electrodes maintain a stable spark voltage, improving combustion efficiency and reducing misfires.
• Reduced Emissions: Efficient ignition leads to more complete fuel burn, lowering unburnt hydrocarbons in exhaust gases.
• Improved Fuel Economy: Precise ignition timing contributes to smoother engine operation and better mileage.

Installation Guidelines

Proper installation is critical for optimal performance. Follow these steps:

1. Ensure the engine is cool before handling spark plugs.
2. Remove the old plug with a spark plug socket and ratchet, taking care not to damage the cylinder head.
3. Check the new plug’s gap using a feeler gauge; adjust if necessary.
4. Screw the plug into the cylinder head by hand until it is snug, then tighten to the manufacturer’s torque specification (typically 140–160 ft‑lb for this model).
5. Reconnect the ignition coil or distributor cap and ensure all connections are secure.
