The NGK 5118 utilizes a high-quality platinum center electrode.
This spark plug requires a 14mm spanner size socket.
While the plug comes pre-gapped, if adjustment is necessary, use a precision gap tool to avoid damaging the brittle platinum tip.
Typical service intervals for platinum plugs range from 30,000 to 50,000 miles, but you should always refer to your vehicle's owner manual for specific maintenance schedules.
No. The NGK 5118 has specific thread lengths and heat ranges. You must check your vehicle’s service manual or NGK's fitment guide to ensure it matches your engine.
Check that the spark plug wire or ignition coil is fully seated on the plug and ensure the gap has not been disturbed.
Back the plug out and inspect the cylinder head threads for debris; never force the plug if resistance is felt.
When installing the NGK 5118, always ensure the engine is completely cool to avoid damaging the cylinder head threads. Use a 14mm spark plug socket to carefully thread the plug by hand until it seats to prevent cross-threading. If using a torque wrench, follow the manufacturer's specified torque settings. Do not apply anti-seize compound to the threads unless specifically required by your vehicle's service manual, as this can affect torque readings. Regularly inspect the electrode condition every 30,000 to 50,000 miles to ensure there is no carbon buildup or abnormal electrode erosion.
