Installation Notes and Tips

Before installation, verify the spark plug gap is set to 1.1 mm as specified. Use a torque wrench to tighten the spark plug to the manufacturer’s recommended torque to avoid damage to the threads or seat. The 14 mm thread diameter and 19 mm reach are compatible with many 4-cycle engines, but always confirm fitment with your vehicle’s specifications. Avoid over-tightening to prevent stripping the cylinder head threads. The flat seat design requires proper seating to ensure a secure seal.
