Key Features
- Standard spark plug design for ignition service and routine replacement.
- Copper core center electrode with nickel tip materials for consistent spark delivery.
- 5,000 ohm resistor helps control electrical noise in the ignition system.
- Flat seat, 10 mm thread diameter, and 14 mm hex for the specified application.
- OEM-recommended 0.032 inch gap listed for most fitments, with a 0.028 inch gap noted for the 2017 YZ250F application.
Detailed Description
NGK 95627, also identified by part number LMAR8G, is a standard spark plug from NGK’s Standard Spark Plug line. NGK is a long-established OE supplier in North America, and this plug reflects original-equipment-style construction with a copper core center electrode, nickel ground and center electrode tips, and a stud terminal. It is specified across Yamaha YZ450F, YZ250FX, WR250F, and YZ250F applications where the listed thread, reach, seat, and heat range match the engine requirements.
This part cross-references 94701-00434 and 94703-00434 for the same application.
What It Helps Address
- Hard starting caused by worn or fouled spark plugs.
- Misfire or uneven combustion from degraded ignition performance.
- Weak spark output when the plug gap is out of specification.
- Ignition noise concerns in systems that use a resistor plug.
- Routine maintenance replacement for specified Yamaha engines.
Installation Notes and Tips
Verify the engine calls for a 10 mm thread, 26.5 mm reach, flat seat, and heat range 8 before installation. Check the gap against the application notes: most listed fitments specify 0.032 inch, while the 2017 Yamaha YZ250F note specifies 0.028 inch. Confirm the plug is tightened to the engine manufacturer’s service specification during installation.
