For Wuling Rongguang, Hongtu, Sailor and other 2000s models, the original-styled replacement NGK 847GP spark plug is a stable choice; electrode material is ordinary nickel alloy, but mature process and precise gap control yield durability that reliably lasts 20,000–30,000 km, performance comparable to OEM parts. OEM number 847GP; thread size M14x1.25; engagement length 26.5 mm; resistance 6 kΩ; bore standard. Functionally, it ensures stable ignition and complete combustion, reducing carbon buildup. Replacement difficulty medium; requires a dedicated socket to torque specifications; recommended for owners with basic DIY skills.
