Below is what we recommend doing to the stock air box lid for those installing our GTM Fuel Kit.
Stock air box lid show below, with two small pieces of tape removed to expose the two rectangular slots in the OEM Guzzi lid.
The stock lid and filter showed (our fine Southwest talcum powder) dust leakage patterns inside the lid.
You can remove the lid entirely over the filter as we did in the dyno thread, or poke it full of holes however you’d like. Start by removing the snorkels. We cut/extended the slots, and added two more as shown. Then a 2” hole (could be 3~4 1” holes too) in the upper portion. Next one we do will be on the top facing upwards. Shown with a superior fitting K&N Filter.
