When should I install the optional box plug?

One of the great benefits of our cold air intake kits is the multiple air flow configurations.

Depending on your airflow requirements, you can gain increased airflow by removing the optional box plug. We recommend removing the plug if your vehicle has other performance upgrades. Keep in mind that you are exposing you filter to more dirt and bugs therefore your filter will need to be serviced/changed more often.

We recommend in warmer temperatures to keep the plug installed to keep out excess engine heat.
