摩托车船外机火花塞 B7HS-10/B8HS-10 94701-00160 94702-00160

If your motorcycle or outboard engine experiences starting difficulties, acceleration jitter, idle instability, or elevated fuel consumption, or exhaust backfires, ignition problems due to worn, carbon-deposited, or excessive spark plug gap. The spark plug normally fires by high-voltage discharge to ignite the air-fuel mixture for smooth power output. Compatible with Honda, Yamaha, Suzuki and other brands after 2000; OEM numbers 94701-00160, 94702-00160; compatible with B7HS-10/B8HS-10 standards. Install with torque wrench; tighten to 20-25 Nm; avoid over-tightening to prevent cylinder head thread damage; ensure spark plug gap 0.7-0.8 mm.
