The K&N Typhoon intake for 2002–2007 Subaru WRX/STI uses a mandrel-bent aluminum tube and an oversized washable, reusable High-Flow air filter with oiled cotton media to increase horsepower and torque. A custom heat shield or airbox helps reduce intake heat; systems commonly install in under 90 minutes. Filter service intervals can reach 100,000 miles under normal highway use; check CARB status for California compliance.
