Motorcraft SP526X Double Platinum Spark Plug
Maintain peak performance and reliability with the Motorcraft SP526X Spark Plug. Engineered by Ford's OEM supplier, this premium spark plug is designed to deliver efficient combustion, smooth engine operation, dependable starts, and consistent power output in modern Ford-based marine engines.
The SP526X features advanced electrode technology that promotes a strong, reliable spark under demanding operating conditions. Whether you're pulling riders, surfing, skiing, or cruising, a properly functioning ignition system is critical for maximizing fuel efficiency, throttle response, and overall engine performance.
