The IAG AOS Street Series Replacement PCV Line Kit is a 27-inch replacement PCV line for IAG AOS installations.

DETAILS

• 27-inch length
• Replacement PCV line for IAG AOS installations
• Universal fitment — suitable for a variety of IAG AOS configurations
• Inspect periodically; replace when stiffening, cracking, or degradation is visible

Why Replace the PCV Line
The PCV line from the crankcase to the AOS canister is exposed to heat cycling, oil mist, and negative pressure over its service life. With age, the rubber can harden, crack, or develop small leaks. A compromised PCV line reduces the effectiveness of the AOS system and can create vacuum leaks in the PCV path.

Service Interval
IAG recommends inspecting PCV lines at regular service intervals. The frequency depends on use intensity — more frequent inspection is appropriate for track-driven or competition vehicles.

Universal Fitment
The 27-inch length accommodates a variety of IAG AOS installation configurations across different WRX and STI applications.

Why Choose IAG Performance

IAG Performance has been building Subaru-specific engine and drivetrain components since 2001, and in that time they have become the standard by which serious Subaru builds are measured. Based in Westminster, Maryland, IAG designs, machines, and assembles their products in-house using Haas CNC equipment and their own engineering team. Their catalog spans everything from short blocks and long blocks rated to 1150 BHP all the way down to the fuel system, oiling, and drivetrain hardware that keeps modified Subarus running reliably for years. Every IAG product exists because a problem needed a better solution than what was available — and the engineering shows.

The RallySport Take

Keep a replacement PCV line on hand alongside your AOS maintenance parts. It is a low-cost item that ensures the AOS system continues to perform correctly when the original line shows signs of age.
