NGK SPARK PLUGS
NGK Spark Plugs for Outboard Engines

NGK spark plugs are designed to operate over a much wider heat range than ordinary plugs. Each NGK features high alumina ceramics for better heat transfer and electrical insulation. Patented triple gasket sealing process eliminates the possibility of combustion gas leakage.

  • They are resistant to carbon buildup and pre-ignition
  • Longer insulator nose prevents fouling and misfiring
  • Solid copper core and nickel-tipped electrode provide a longer plug life

I've used NGK plugs often in the past and have never been disappointed. I recently replaced the old plugs in my Mercury outboard, and was stunned at the difference new NGK plugs made versus just cleaning and re-gapping the old ones (not NGK, came with the motor). The motor starts faster, and idles and runs much smoother at speed than it did before the change.

I used the internet and the catalog on hand to find the product I needed, the clerk was able to direct me to the catalog, he was of no help as far as knowing product. I think it would be beneficial if there was a computer kiosk that could help you find the product you need for the vessel, engine you have.
