NGK Spark Plugs for Marine Engines

NGK spark plugs are trusted by boat owners and engine manufacturers around the world. They deliver reliable starts and consistent performance on the water.

As the original equipment supplier for over 90% of outboard engines, NGK knows what marine engines need. Their spark plugs are designed to handle the tough conditions of saltwater use.

Whether you're replacing plugs in an outboard engine, PWC or inboard motor, our NGK range offers proven, marine-ready options.

Each plug is built with corrosion-resistant plating and a pure copper core. This helps reduce fouling, improve heat dissipation and prevent overheating. They also resist RFI interference and support quicker cold starts.

At Force 4 Chandlery, we stock a wide selection of NGK marine spark plugs. Our range suits popular outboard brands like Yamaha, Mercury, Honda, Suzuki and more.
