NGK 4929 Standard Spark Plug (DPR8EA-9) - Nickel Electrode, Fits Honda, Kawasaki, Suzuki, Yamaha ATV and Motorcycle Engines

The NGK 4929 is a Standard series spark plug built on NGK's long-running nickel-electrode design, used as an OE-grade replacement across a wide range of small-engine applications. It uses a solid copper core center electrode for strong heat dissipation and conductivity, paired with a nickel ground electrode and nickel center electrode tip for dependable, economical service life. The ceramic insulator is built with a corrosion-resistant plated shell to make installation and removal easier and to help prevent seizing over time. A 5000 ohm resistor design helps suppress electrical interference during operation.

This plug carries a 12mm x 1.25 thread size and is intended as a direct fit for the engines listed in the Fitment section below, spanning ATV and motorcycle applications from Honda, Kawasaki, Suzuki, Yamaha, Ducati, KTM, MZ, Triumph, and Midwest. Always check your engine's owner or maintenance manual to confirm the NGK 4929 is the correct plug for your specific engine before installing, since using the wrong plug can reduce performance and fuel economy or cause engine damage.
