The 90-degree Elbow
from the stock airbox goes there. If the filter is positioned with the hole toward the bottom, the air line is not seen.
This is an airpump line that pumps filtered air into the exhaust headers during startup fuel enrichment cycle to help burn off the additional fuel. EPA deal.
The purpose of fitlered air is to prevent a rock from going into the pump and causing damage to the pump.
Use the same 1" hose, route under the filter and hook it up.
We didn't put the hole there for nothing.
