GrimmSpeed Cold Air Intake System Black Subaru 2002-2007 WRX / 2004-2007 STI

The design requirements for this intake are similar to our others: the intake should reduce as much restriction as possible, it should be easy to tune and accurately measure incoming airflow, it should properly filter out potentially harmful particles, and it should look like something you’re proud to have in your engine bay. We designed this intake to meet these goals by using only minimal bend angle and pipe length which helps to decrease restriction.  Additionally, our low restriction washable air filter helps here too, while still filtering particles down to 5 microns.  We have also incorporated an air straightener into our design, an invaluable feature that was not utilized on the OEM airbox until later models.  Finally, we have continued our “Stealthbox” heatshield design, utilizing it to not only keep hot air away from the air filter, but to cover up unsightly components such as the ABS pump. Less obvious features of this intake include the location of the air filter.  Specifica
