Subaru K&N Filters & Cold Air Intakes

K&N Oil Filters and Intakes for Subaru

K&N HP-1004 oil filters for EJ and FA Subaru engines, with a wrench-off nut so you never fight a filter again, plus K&N Typhoon cold air intakes for the 2017–2023 and 2024+ Crosstrek and Impreza. The intake pairs with our Billet Power Blocks: the BPBs lengthen the intake runners so a freer-flowing intake actually does something.

The HP-1004 is the filter we include in every short block install kit.
