IAG In-Line Check Valve for Street Series AOS | 2002-2004 Subaru WRX | RPL-718XCV

Video description

Installing an IAG Street Series Air Oil Separator on your 2002-2004 Subaru WRX? This IAG In-Line Check Valve is the missing piece needed to properly adapt the IAG Street Series AOS (IAG-ENG-7180) to early EJ20-powered WRX models.

The factory PCV valve on 2002-2004 WRXs features a larger diameter than later EJ engines, preventing the standard Street Series AOS kit from installing correctly. This check valve solves that compatibility issue, allowing you to complete your installation with proper PCV system operation.

Fitment:
Subaru WRX (2002-2004)

Features:
- Adapts the IAG Street Series AOS (IAG-ENG-7180) to early EJ20 WRX models
- Designed specifically for 2002-2004 Subaru WRX
- Installs using the supplied 3/8" hose from the AOS kit
- Directional arrow ensures correct airflow when installed toward the intake manifold
- Genuine IAG replacement component

Important Installation Note:
Removing the factory PCV valve leaves an opening that must be filled. To complete the installation, you'll also need the updated Subaru OEM Intake Manifold Fitting (14076AA030), sold separately.

Fitment Information:

2002-2004 Subaru WRX

Features:

Looking to adapt the IAG-ENG-7180 IAG Street Series AOS to your 2002-2004 WRX? The factory PCV valve is much larger in diameter on early EJ20 engines, not allowing the standard 7180 kit to work on WRX models produced from 2002-2004. Using the provided 3/8" hose from the AOS kit, install this check valve with the directional arrow pointing towards the intake manifold.

ADDITIONAL PART NEEDED:

Removing the factory PCV leaves a hole that needs to be filled! In addition to the check valve, this updated factory intake nipple will be needed to complete your transfermation.

PCV check valve

Works like new. 1 way valve. Direction matters. Arrow toward motor. I could push air backward through the old one after 75k miles.

Does what it's supposed to

Old one failed after five years and my car was running funny (high idle, etc). Swapped it out and it's good to go.
