The IAG Air/Oil Separator (AOS) is a must - have for your Subaru. After years of testing on both standard and competitive setups, it offers top - notch protection for your 2006 - 2007 Subaru WRX, 2004 - 2007 STI, and 2005 - 2008 Forester XT engines. This AOS features a 1 - liter cast aluminum swirl pot canister that greatly enhances oil separation from the PCV system. Its lightweight yet sturdy aluminum housing provides better ventilation, and an intelligent baffle design makes it stand out. It's compatible with all fuel types, extends engine life, and works well with standard ECU settings. The included SAE Quick Connection lines simplify installation and reduce leakage risks, giving your engine a polished, factory - like look. Note that it's not compatible with most aftermarket strut tower bars. The AOS comes fully assembled with hardware, lines, and fittings, and can be easily disassembled for cleaning. It keeps oil out of the intake and minimizes condensation build - up. For 2002 - 2004 Subaru WRX owners, additional parts (IAG - RPL - HSE - EJ - PCV, 14076AA030) are needed, and the factory cruise control module must be moved or deleted.
Using the IAG Air Oil Separator is easy. First, check your Subaru's model year to ensure it's compatible. If you have a 2002 - 2004 WRX, make sure you have the additional parts and follow the cruise control module relocation instructions. The AOS comes fully assembled with all the necessary hardware, lines, and fittings. Use the included SAE Quick Connection lines for installation; they're designed to make the process simple and reduce the chance of leaks. Once installed, it'll blend in nicely with your engine. When it comes to maintenance, you can easily disassemble the AOS with a single Allen wrench. Just remove two bolts, and you can clean each part. Remember, this AOS isn't compatible with most aftermarket strut tower bars, so check your setup before installation. Regularly inspect the AOS to keep your engine running smoothly and protected.
