Grimmspeed DRY-CON Performance Panel Air Filter For Subaru 08-21 WRX 08-18 STIGRM 060091 Better Flow, More Power! At GrimmSpeed we know that not everyone is ready for one of our full aftermarket intake systems, but still wants a safe and easy way to increase power with no tuning required. We worked hard to develop a direct replacement, dry element air filter for the stock airbox that not only decreases restriction, producing more torque and horsepower, but is also able to filter out particulates at the same level as the OEM

Each kit also includes our unique two-piece splitter design that replaces the factory engine cover with a splitter design that's made to fit the larger core of the GrimmSpeed TMIC

The COBB Fiesta ST Intercooler Upgrade is a direct replacement of the factory piece and is the easiest modification to make for a drastic increase in cooling and power
