NGK BZ7HS-10 Spark Plug for Outboard Motors

Hard starting on a cold morning, then rough idle until the engine warms up. That's usually a plug that's lost its edge. The NGK BZ7HS-10 is built to fire cleanly from the first crank. Trivalent metal plating keeps the thread free after months of salt exposure. Triple seals stop oil seepage before it fouls your next launch. The copper core wicks heat away from the combustion chamber so the engine stays in its sweet spot. Corrugated ribs block flashover paths that cause misfires under load. Pure alumina silicate ceramic insulator holds structural integrity where budget plugs fail after one season. Drop it in, torque it, and the hard-starting's a thing of the past. Add to cart
