Using proven-fit parts designed for the YFM450 Grizzly minimizes installation hassles and helps you avoid mismatched components.

Installation tips

• Prepare the airbox area: remove debris and ensure the sealing surface is clean before installing the new air filter.
• Replace the oil filter with the engine warmed up and the drain plug secure, following the manufacturer’s torque specs for the oil drain and filter.
• Install the spark plug with the correct gap and torque; use the recommended wire routing to avoid incorrect grounding.
• If you’re adding the optional fuel filter, place it in a secure position away from heat sources and ensure proper fuel-line routing to prevent kinks.
