NGK BPR7HS Standard Spark Plug – OEM Replacement for ATVs, UTVs, Motorcycles & Small Engines – NGK 6422

Ensure reliable ignition and peak engine performance with the NGK BPR7HS standard spark plug – the OE-approved, factory-specified replacement for thousands of motorcycles, ATVs, UTVs, and small-engine applications . As the world leader in spark plug technology with over 80 years of manufacturing expertise, NGK delivers consistent spark, superior durability, and trouble-free operation .

Features a 98% pure copper core for increased heat dissipation and reliable starts, cold-rolled threads to prevent cylinder head damage, and trivalent metal plating that eliminates the need for anti-seize . The projected tip design and 2.5mm nickel-alloy center electrode improve ignitability for better combustion efficiency .

Built with NGK's high-grade alumina silicate ceramic for superior strength and heat transfer, plus triple seals to prevent leakage . The integrated 5k Ohm resistor suppresses electromagnetic interference (EMI/RFI) to protect sensitive ECU, communication, and audio systems .

⚠️ Important Variant Note – BPR7HS vs BPR7HS-10:

This listing is for the NGK BPR7HS (Stock No. 6422) with a 0.7mm (0.028") pre-set gap. NGK also manufactures a BPR7HS-10 (Stock No. 1092) variant with a 1.0mm (0.039") pre-set gap .

Always verify your vehicle's specified spark gap in your owner's manual before ordering. Installing an incorrect gap can cause misfiring, poor performance, and engine damage.

Why Choose NGK BPR7HS?

NGK is the world's largest supplier of OEM spark plugs, trusted by manufacturers globally for over 80 years . The BPR7HS is engineered to meet or exceed original equipment specifications, delivering:

• 98% pure copper core – Superior heat dissipation for reliable starts and protection against overheating 

• Projected tip design – Positions the spark deeper in the combustion chamber for improved ignitability and fuel efficiency 

• Nickel-alloy electrodes – Provides consistent wear resistance and extended service life 

• 5k Ohm resistor – Suppresses electromagnetic interference (EMI/RFI) that can disrupt ECUs, communication systems, and audio equipment 

• Cold-rolled threads – Prevents cross-threading and costly cylinder head damage 

• Trivalent metal plating – Superior corrosion and anti-seizing properties; no anti-seize compound required 

• Triple-gasket sealing – Virtually eliminates combustion gas leakage past the shell 

• 5-rib insulator design – Prevents flashover for consistent spark delivery 

Recommended Usage:
Best for vehicles equipped from the factory with nickel-alloy spark plugs. Not recommended for vehicles originally equipped with precious metal (iridium/platinum) plugs .

Torque Specification:
NGK recommends 12–12.7 ft-lb (17.2 Nm) for 14mm gasket-seat spark plugs. Always use a torque wrench.

Genuine NGK replacement components are designed to meet or exceed original equipment specifications. Trust the original.
