Product Description
This Process West cold air intake kit replaces the factory air intake on Subaru Impreza 2001-2002 (GD/GG Bugeye); Subaru Impreza 2003-2005 (GD/GG Blobeye); Subaru Impreza 2006-2007 (GD/GG Hawkeye), using lightweight CNC mandrel-bent aluminium tubing with a machined mount for the standard mass airflow (MAF) sensor.
This kit uses a 72mm diameter MAF housing in place of the standard 66mm unit, for increased airflow into the induction tract. The mass airflow sensor will need to be re-scaled, or the ECU remapped, before the car is driven.
A K&N high-flow air filter is included, and the kit is finished in black.
