Does IAG have an Air Oil Separator that fits the 2002-2005 WRX?
We do not make an AOS specifically for the 2.0L vehicles. You can purchase one for a 2006-07 WRX and relocate your cruise control. Additionally, the 2002-2003 WRX features a PCV nipple on the throttle body that also houses the PCV valve. This differs from 2004-07 STI’s, as they simply use a valve-less nipple at the same location.
The picture below shows the difference between the two nipples.
- 2002-03 WRX PCV Nipple Part # 11810AA000
- 2004-07 STI Valve-less Nipple Part# 14076AA030
If you are attempting the AOS install on a 2002-2003 WRX you will need to swap your PCV Nipple for the 2004-07 STI valve-less nipple PN# 14076AA030 found here.
