NGK 4339 Standard Spark Plug, Fits PWC 02-08 and BRP Ski-Doo 03-08

The NGK 4339 is a standard NGK spark plug built for reliable ignition performance in personal watercraft and BRP Ski-Doo applications. It uses a solid copper core center electrode for superior heat dissipation and conductivity, paired with a nickel center electrode tip and a nickel ground electrode in a standard ground configuration. The plug carries a 5000 ohm resistance rating to help suppress electrical interference during operation. Like other NGK standard plugs, it is treated with a corrosion-resistant plating that makes installation and removal easier and helps guard against seizing in the cylinder head over time. NGK's broad heat range design on this plug is intended to keep combustion temperatures in a stable operating window across varying loads and RPM, which supports consistent starting and running performance. This spark plug is intended to fit PWC (personal watercraft) applications from 02-08 and BRP Ski-Doo applications from 03-08. Always confirm the correct spark plug against your engine and maintenance manual, since using the wrong plug can reduce fuel economy, reduce performance, or cause engine damage.
