Champion has spark plugs for inboards (including those that require glow plugs), outboards, jet boats and more. Champion uses an extruded copper core in our center electrode that maintains accurate control of heat range, optimizing the performance and longevity of the spark plug. Champion’s marine plugs also have stainless steel threads that never rust, are easy to remove and are particularly well-suited for saltwater environments.

Other benefits of Champion’s marine plugs include:

• Reduced radio frequency interference — Champion’s patented Mag Suppressor provides maximum protection from “radio noise” and interference in GPS/fish finders.
• Heat-Active™ alloy — provides maximum heat dissipation and conductivity

Champion PowerSport marine plugs give you a dependable start and keep you going — wherever you’re going.
