PERRIN Drop-In Filter Foam - Black for Select 2005-2014 Subaru Forester, WRX STI, and Legacy
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits select 2005-2014 Subaru Forester XT, Impreza WRX STI, and Legacy GT models.
The PERRIN Drop-In Filter Foam (PSP-INT-110) replaces your restrictive factory paper element with a high-flow, multi-layer foam design.

- Washable and reusable for a long service life
- Stealth black finish
- Manufacturer Part Number: PSP-INT-110
