The NGK BP6HS-10 (part number 6326) is a high-quality, reliable spark plug designed for small engines, motorcycles, and marine applications that require a robust ignition source with a projected centre electrode. Ideal for enthusiasts and professional mechanics alike, this plug offers exceptional durability and consistent firing performance through its nickel middle electrode construction; however, users should note that it features no internal interference suppression, making it best suited for older or less sensitive ignition systems.

This spark plug requires a 20.8 mm spark plug socket.
No, the BP6HS-10 does not contain internal resistance for radio frequency interference suppression.
Yes, the BP6HS-10 is a common cross-reference for the Champion PL7YC.
Replacement intervals depend on usage, but it is recommended to inspect it every 3,000–5,000 miles or annually for marine applications.
The '10' refers to the factory-preset gap of 1.0 mm.
Yes, the SAE connector is unscrewable to accommodate different spark plug cap types.
Check the spark plug gap to ensure it matches your engine manual, and inspect the ignition wire for cracks or poor connectivity.
Remove the plug to check for heavy carbon deposits or a wet electrode, which suggests flooding; clean or replace the plug if fouling is severe.
Ensure the rubber boot is seated fully on the SAE connector and that the porcelain insulator is clean and free of moisture or oil.
Before installation, ensure the engine is completely cool to prevent thread damage. Always verify the gap setting according to your engine manufacturer's specifications, as the BP6HS-10 may arrive set for a specific factory application. Use a 20.8 mm spark plug socket for proper fitment to avoid damaging the ceramic insulator. When tightening, thread by hand initially to avoid cross-threading, then use a torque wrench to reach the manufacturer’s specified torque setting for a gasket seat plug. Periodically inspect the electrode for color—a light tan color indicates ideal combustion, while excessive black carbon buildup may indicate a need for a tune-up or a slight adjustment to the fuel-to-air mixture.
