A known flaw in 2017-2021 KTM/HSQ filter cages is the center support. It’s aggressive x pattern will damage air filters, possibly leading to severe engine damage. This cap solves this issue. This will not fit filter cages with large X pattern, only the small pattern.
I highly encourage to purchase another item, as this part is cheaper than shipping cost. Your second item and every item after is no additional shipping cost.
Please make sure fitment of this part is compatible with your bike.
