Subaru Impreza WRX/STI 02-Up Turbo Air Box Intake Hose. Made with the highest-grade space age silicone available in the industry and can withstand high temperatures as well as high airflow for performance air intakes. Non-flammable and will keep its flexibility and elasticity for duration of the car. Smooth inner structure to increase the air flows. This hose goes after the MAF sensor to the turbo inlet hose and helps the turbo spool up time faster and increases boost. A direct replacement for the weak factory plastic hose. When combined with the turbo inlet hose (see below), a dramatic increase of 3 to 5 of WHP is easily obtained! Easy to install.
