Dryflow filters provide the same level of protection as an oiled filter, but require less maintenance, are less of a mess, and have no risk of over-oiling. The rigid screen inside and around the filter media helps in preventing damage from debris and are ideal for dusty and rough driving conditions.
REMOVE FILTER: Remove filter from the intake pipe and lightly tap off all loose dirt and debris.
APPLY CLEANER: Liberally spray Dryflow cleaner onto both sides of the filter, with the majority of it applied to the dirty side. Allow to soak in for 10 minutes. Do not allow it to dry on the air filter.
RINSE FILTER: Rinse off the filter element with cool or warm (not hot) water from the clean side out in order to flush the dirt out of the filter. It may be necessary to use your fingers on the hose, to apply light water pressure. Repeat steps 2 and 3, until the water flowing through the media is completely clear of any dirt and debris.
DRY AND RE-INSTALL FILTER: After rinsing, gently shake off excessive water and allow to dry naturally or carefully use compressed air to help speed the drying cycle. Re-install the filter onto the intake system, airbox or custom assembly once it is dry or just slightly damp. Follow all original installation instructions.
This is a direct replacement for PERRIN Performance 2015-2019 WRX & STI intake systems. This filter will also work on any intake system which accepts a 2.75" filter.
PERRIN Performance warrants to the original purchaser that all PERRIN products will be free from defects in material and workmanship within a sixty (60) month period from the date of purchase. *Some exclusions apply
