Blitz Sonic Power Air Intake

Blitz Sonic Power Air Intake System for Subaru WRX / STI utilizes a four layer cotton filter with a stylish and effective aluminum outer shell. The aluminum outer shell acts as a adjustable velocity stack shield that produces a unique suction sound while at the same time, increases intake velocity. Hot engine bay air and reduced air turbulence are also achieved with the outer shield. Cooler air and increased air velocity equates to increase horsepower and torque.
