Subaru Impreza Cold Air Intake System Frequently Asked Questions

Can I install my new Cold Air Intake myself?

If you have a decent amount of technical knowledge and can follow instructions, you should be able to follow the instructions and install a cold air intake onto your Subaru Impreza yourself. K&N FIPK intakes by far offer the best instructions with multiple pictures, though AEM is close behind.

What kind of power can I expect to get on my Subaru Impreza from an AEM, Spyder, or K&N FIPK Cold Air Intake?

Power increases vary by application, but you could expect anywhere from a 3-15hp increase under optimal conditions.

Are Cold Air Intakes safe in the rain?

NO CAR should ever be operated during flooding. Unlike short ram intakes, cold air intakes draw air from a relatively low position. Your vehicle can technically ingest water from rain puddles, streams, floods, etc if your car is lowered or the water is deep enough, and damage your engine. To prevent this, you could install the appropriate sized AEM Bypass valve onto your Subaru Impreza's AEM or Spyder Cold Air Intake, however, we instead recommend switching to your vehicles stock intake system if you anticipate driving through flood conditions. K&N FIPK Intakes do not require bypass valves since their design is higher than AEM and Spyder, and are relatively safe from water ingestion.
