The K&N adapter 63-1089 (number 430) is a compact connection piece that increases air filter fitment options by matching aftermarket filters to nonstandard intake interfaces. Intended for retrofit and special-application use, it simplifies installation where a direct fit isn’t available. Backed by K&N warranty, the adapter supports expanded filter compatibility without major intake modification.
