OVERVIEW

This complete oil change and tune-up kit provides all essential components for routine maintenance on Yamaha Big Bear 400 and Kodiak 400 models, ensuring cleaner lubrication and reliable engine protection in rugged conditions. The package supplies four quarts of Moose Offroad 10W-40 motor oil, a premium HifloFiltro oil filter, and an NGK D(R)8EA spark plug to deliver a comprehensive service solution that meets critical upkeep needs.

ENGINEERING & PERFORMANCE

The Moose Offroad 10W-40 oil maintains stable viscosity under intense heat and heavy loads, ensuring consistent film strength and reduced friction during demanding rides. The included HifloFiltro filter employs specialized media and passes 16 quality-control inspections to provide reliable debris capture comparable to factory standards. Meanwhile, the NGK D(R)8EA spark plug utilizes a copper core, trivalent corrosion-resistant plating, and a triple-seal design to promote rapid heat transfer and persistent ignition performance.

WHY RIDERS CHOOSE THIS

Riders select this kit because it replaces aging components with matched parts that address common wear patterns specific to Yamaha's 400cc utility platforms. The viscosity-stable oil actively combats thinning caused by sustained trail heat while lowering internal drag, and the HifloFiltro filter's rigorous testing ensures long-term debris retention that protects sensitive bearings. Paired with the NGK plug's heat-dissipating copper core and durable seals, this combination delivers steady lubrication and crisp throttle response exactly where stock replacements may fall short.
