Founded over 80 years ago, NGK is a Japanese brand that actually needs no introduction: its spark plugs are known to everyone who has ever chosen such parts for the ignition system. Reasonably combining effective innovations and tried-and-tested solutions, NGK plugs are famous for their lasting lifespan, excellent performance, and reliability. They are extremely popular and can be found not only in cars and trucks but also in all-terrain vehicles and powerboats. The company's assortment covers almost all existing models of personal watercraft and about 90 percent of outboard motors, so you're likely to find what you need.
Although marine spark plugs have the same working principle and materials as their automotive counterparts, they may have some differences aimed at the better operation of some engine models. A plug may feature a specific resistor, heat rating, and gap, while the trivalent plating of NGK plugs provides good salt spray resistance. A high-grade copper core and alumina ceramic enable these ignition components to dissipate heat as effectively as possible; in addition, marine plugs undergo severe thermal shock testing to make sure the product can withstand water splashes. Apart from the abovementioned goods, NGK offers ignition coils, wire sets, oxygen sensors, and some other products used in various industries.
