Step 13: This kit includes an optional plug to close off the auxiliary air inlet. Install the plug if you wish to only capture cold air from the factory inlet. · Without the plug installed, the Takeda intake will capture the maximum air available. More airflow offers more power, yet some of this air is picked up from inside the engine compartment and could be warmer, which will affect the performance of the vehicle. · The plug installed on the housing will block off any hot engine air entering the housing to make sure the coolest air available is directed into the engine. Intake noise will also be reduced using the plug
