Part number 7784, the C-series 10mm thread design is engineered for the tight combustion chamber geometry of high-revving PWC engines, where a standard 14mm plug simply won't fit.\u003c\/p\u003e\u003cp\u003eThe projected tip (B-suffix) improves ignitability in the compact combustion chamber, while the built-in resistor suppresses radio frequency interference — important in watercraft where electronics and communication equipment are in close proximity. NGK's triple gasket sealing process eliminates combustion gas leakage, and cold-rolled threads protect the cylinder head on installation.\u003c\/p\u003e\u003cp\u003eSold in a 4-pack.

PWC engines run at very high RPM and are sensitive to plug condition, so replacing plugs at the manufacturer's recommended interval (typically annually or every 50–60 hours) is more important on a PWC than on a lower-revving outboard engine.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e This product currently has no image on file.
