Hello, Ive got a WRX 2004 UK car. I want to change the PCV valve but everywere I look theres 2 different partnumbers to choose from. Do any of you who actually bought a PCV valve and put it on the car saved the partnumber so that I KNOW that it fits. I have seen both numbers in parts catalogues and different forums tells me either on or the other.

These are the 2 numbers I got: 11810AA000 and 11819AA001.

Thanks for the help,
Per
