NGK 6326 Standard Spark Plug BP6HS-10 for Mercury, Force, Nissan, Tohatsu Outboards and Yamaha Engines

The NGK 6326 is a Standard Spark Plug identified by reference number BP6HS-10, built on NGK's proven standard-plug design for small marine and recreational engines. It is treated with corrosion-resistant plating to keep installation and removal easy over the plug's service life, and it uses a solid copper core center electrode for strong heat dissipation, reliable conductivity, and a broad operating heat range. Both the ground electrode and the center electrode tip are nickel, paired with a standard ground electrode configuration (as opposed to a surface-discharge or V-cut design), and the plug carries 1 ohm of resistance.

The NGK 6326 / BP6HS-10 is intended as an OE-type replacement for a specific set of outboard and small engines: Yamaha motorcycle engines (1987-1986), Force (U.S. Marine) outboards (1994-1990), Mercury outboards (1985-1983), Nissan outboards (1996-1985), Tohatsu outboards (1996-1980), and Kawasaki PE engines. Always check your engine's maintenance manual to confirm this is the correct plug for your specific engine, and install only as recommended by your engine's original equipment manufacturer -- using the wrong plug can reduce performance and fuel economy or damage the engine.

Frequently Asked Questions

What engines does the NGK 6326 spark plug fit? The NGK 6326 (reference BP6HS-10) fits Yamaha motorcycle engines from 1987-1986, Force (U.S. Marine) outboards from 1994-1990, Mercury outboards from 1985-1983, Nissan outboards from 1996-1985, Tohatsu outboards from 1996-1980, and Kawasaki PE engines. Always confirm against your engine's maintenance manual before ordering.

Is the NGK 6326 the same plug as BP6HS-10? Yes, BP6HS-10 is the reference number stamped on the NGK 6326 Standard Spark Plug -- they are the same part.

What is the center electrode made of on this spark plug? The NGK 6326 uses a copper center electrode core with a nickel tip, which supports strong heat dissipation and conductivity across a broad heat range.

Does the NGK 6326 use a resistor design? The NGK 6326 spark plug is rated at 1 ohm of resistance with a standard ground electrode configuration, not a surface-discharge or resistor-focused design.

How many spark plugs come in one NGK 6326 order? Each NGK 6326 order is packaged as a single spark plug (1 count).

Is this a genuine NGK spark plug or an aftermarket copy? The 6326 is a genuine NGK Standard Spark Plug, part of NGK's original standard-plug lineup rather than a third-party copy.

What is the thread size on the NGK 6326? The NGK 6326 spark plug has a #2-56 thread size.

Will the NGK 6326 work in my Mercury outboard? It fits Mercury outboards from the 1985-1983 model years specifically; check your Mercury engine's manual to confirm it matches your model year before ordering the 6326.

How is the NGK 6326 different from NGK's V-Power spark plugs? The 6326 is a Standard Spark Plug with a standard ground electrode configuration, while NGK's V-Power plugs use a V-shaped cut in the center electrode to help direct spark development -- the 6326 relies on its copper core and broad heat range instead.

What material is the ground electrode on the BP6HS-10 plug? The ground electrode on the NGK BP6HS-10 (stock number 6326) is nickel, matching the nickel center electrode tip.

Are there OEM cross-reference numbers for the NGK 6326? Yes, the NGK 6326 cross-references to Mercedes-Benz A0001594303 and A0021597203, and Opel 1214018, 1214044, and 1214801.

What does corrosion-resistant plating do on this spark plug? The plating on the NGK 6326 resists corrosion so the plug threads in and out of the engine easily over repeated maintenance intervals.
