Spark plugs with the same 14 mm thread diameter can still differ in reach, heat range, seat style, terminal type, resistor design, projection, and required gap. Installing the wrong plug can cause hard starting, misfire, poor idle, overheating, thread damage, piston contact, or ignition-system issues.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eWhen This Part Needs Replacement\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eReplace spark plugs during scheduled tune-up service or whenever the plug is worn, fouled, fuel-soaked, oil-contaminated, cracked, corroded, damaged, or causing hard starting, rough idle, hesitation, misfire, weak acceleration, or poor throttle response. Marine outboards and seasonal equipment should have plugs inspected regularly because long idle time, old fuel, oil mixture, moisture, and storage can accelerate fouling.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eInstallation Notes\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eCheck the plug number and required gap before installation. Install into clean, undamaged cylinder head threads and tighten to the engine manufacturer's torque specification for the exact engine. Because this is a gasket-seat plug, confirm the sealing washer is present and seated correctly.\u003c\/p\u003e\n\u003cp\u003eAvoid adding anti-seize unless the engine or spark plug manufacturer specifically calls for it, as thread lubricant can change clamping load and increase the risk of over-tightening.
