  High Flow Intake
This used to be an easy way for owners of turbocharged cars to add gobs of power. Technology advances, though, and the newest factory-built intakes are much better. Horsepower gains from intake systems on the WRX are smaller, but there still are a few horsepower (maybe 5) to be gained, and as other modifications increase, the added power will go up as well.
The K&N intake pictured above is one of our most popular systems.
