This is a genuine Cobb Tuning replacement air filter for the 2015-2021 WRX Big SF Intake.

The filter element that originally came with your SF Intake is cleanable and can be reused for the life of your car. However, should your filter element become damaged or lost, this is the replacement part.

This is a filter only, not a whole intake system.

Fits 2015-2021 WRX (only) Cobb SF Intake kits.
