Spark Plug D8EA | Nickel V | groove Marine Ignition | 4Boats

NGK D8EA nickel spark plug features a V‑groove centre electrode designed to improve ignitability and provide reliable performance in marine conditions. Compatible with many small outboard and portable engines.

• Nickel-plated shell helps resist corrosion in saltwater environments while providing dependable conductivity
• V‑groove centre electrode improves ignitability and consistent spark formation
• Common specs: thread M14×1.25; reach ~19 mm; hex size 16 mm; typical gap 0.7 mm (0.Ø 28 in) - confirm gap before fitting
• Heat range D8EA suited to many two- and four-stroke outboards, personal watercraft, portable generators and other small utility engines
• MPN: D8EA. Resistor variant: DR8EA (verify whether a resistor or non-resistor plug is required for your ignition)
• Typical compatible applications include small outboards and portable engines; always check fitment for your specific model via our compatibility resources
• Replace as part of routine maintenance to maintain performance and minimise fouling in marine use

Before fitting, confirm thread size, reach, hex size, resistor vs non-resistor requirement, recommended torque and acceptable gap for your engine. See our compatibility guide and torque guidance for fitment help, or contact us if you need assistance selecting the correct plug.
