The Kawasaki 99969-6671 Tune-Up Kit is the comprehensive, factory-authorized maintenance solution for the popular FR and FS series V-Twin engines.

Features:

• Dual-Stage Air Filtration: Includes a high-density pleated paper filter and a washable foam pre-cleaner. This combo is designed to meet OEM standards for dust-holding capacity, protecting your engine in dry, high-debris mowing conditions.
• High-Zinc K-Tech™ Oil: Comes with two quarts of 10W-40 K-Tech oil, which is specifically formulated with anti-wear additives to protect critical internal components like camshafts and lifters from heat-related scuffing.
• High-Pressure Oil Filter: Features the upgraded 49065-0736 filter, built with a heavy-duty canister and a silicone anti-drain back valve for instant lubrication during every start.

• Active Fuel Cleaning: The included fuel filter captures microscopic sediment, preventing the clogged injectors or jets that lead to engine surging and uneven idling.

• Optimized Ignition: Two pre-gapped NGK spark plugs ensure consistent spark timing, maximizing fuel combustion and reducing carbon buildup.
