Product Description: This F6RTC spark plug uses nickel-alloy electrodes and is a universal ignition accessory suitable for garden machinery, generators, and various utility vehicles, ensuring stable and reliable ignition. Key Features: Model: F6RTC, Thread: M14×1.25mm, Reach: 20.8mm, Total Length: 81mm, Engagement Length: 19mm. Compatible with most engine interfaces with the same specification. Material: The electrodes are made of nickel alloy, resistant to high temperatures and corrosion, for an extended lifespan. The insulator is made of high-quality ceramic (insulation resistance: 0.12Ω), ensuring stable high-voltage ignition. Performance: Electrode gap: 0.1mm, Resistance: 2Ω. Moderate resistance, precise ignition, improved fuel efficiency, and reduced fouling. Wide Applications: Compatible with garden machinery (lawnmowers, etc.), generators, vans, and other vehicles/equipment, this product offers great versatility. It can be used as an original equipment manufacturer (OEM) replacement part to meet the ignition needs of various electrical equipment. Quality and Manufacturing: Manufactured under our own brand with meticulous craftsmanship. The ceramic insulating layer is securely attached to the metal casing, ensuring vibration and aging resistance and guaranteeing stable operation even under harsh conditions.
