Rain Sock
See Figure 1. In wet or rainy conditions, because the filter element is exposed, water can enter the engine. When parked, water can cause internal engine corrosion or damage. When running, water can cause the engine to misfire.
In wet or rainy conditions, install the rain sock (8) over the air cleaner assembly to prevent water intrusion.
