Spark Plug.

Superior construction for serious power.

Versatile plugs with wide operating heat ranges prevent fouling from running too cool and preignition from running too hot.

Features high alumina ceramics for improved heat dissipation and electrical insulation, deep-seated copper core for a wider heat range and a nickel alloy tip for longer life.

Engineered with precision for your boat´s motor, the NGK DPR7EA-9 incorporates advanced features that deliver tangible benefits. The built-in resistor is a critical component for modern vessels, effectively suppressing ignition noise and electromagnetic interference (EMI). This protects sensitive marine electronics such as your GPS, fish finder, and radio systems, ensuring they operate without disruption from the engine´s ignition system.

Durability is paramount in a harsh marine setting, and the DPR7EA-9 excels with its Trivalent Metal Plating. This superior finish provides exceptional anti-corrosion and anti-seizing properties, making it highly resistant to the damaging effects of humidity and saltwater. This not only guarantees a longer service life but also simplifies installation and removal during maintenance, preventing seized plugs in the cylinder head.

Every component is designed for performance. The corrugated ribs on the high-grade alumina silicate ceramic insulator prevent flashover, ensuring the ignition energy is directed to the spark gap and not lost. This translates to more reliable starts and eliminates misfires that can lead to poor performance and increased emissions. The solid copper core provides superior heat transfer and dissipation, helping to maintain the optimal operating temperature. This capability, combined with the nickel alloy electrode, ensures this spark plug provides consistent performance and an extended lifespan, reducing the frequency of replacements and giving you more time to enjoy the water.

Choose the NGK DPR7EA-9 for your marine engine and experience the difference that world-class engineering makes. It’s the ideal solution for boat owners looking to enhance engine performance, protect vital electronic equipment, and ensure maximum reliability from their outboard or inboard motor
