Protection for Your Engine: The IAG Air/Oil Separator is a great investment for your Subaru. After years of testing in standard and competitive situations, it offers top - notch protection for your 2006 - 2007 Impreza WRX or 2004 - 2007 STI engine. It has a 1 - liter cast aluminum swirl pot canister that does an excellent job of separating oil from the PCV system before the gasses go back to the intake. Made of lightweight yet durable aluminum, it has better ventilation and a smart baffle design. It works with all fuel types, extends engine life, improves crankcase ventilation, and fits well with standard ECU settings. SAE Quick Connection Lines: The IAG Air Oil Separator comes with a full set of custom - length SAE Quick Connection lines. These lines make installation easier and reduce the risk of leakage as they provide a more reliable and secure connection than basic hose clamps. Once installed, it has a polished, factory - like look that matches your Subaru's engine. Please note: This AOS is not compatible with most aftermarket strut tower bars. AOS in the Box: It's ready to install, and all the hardware, lines, and fittings are included. It arrives fully assembled but can be easily taken apart for cleaning with a single Allen wrench. Features: It keeps oil out of the intake and minimizes condensation build - up. Additional Information: For 2002 - 2004 Subaru WRX customers, additional parts (IAG - RPL - HSE - EJ - PCV, 14076AA030) are needed, and the factory cruise control module must be moved or deleted. You'll also need the cruise control module relocation instructions.
Using the IAG Air Oil Separator is easy. First, make sure your Subaru model (2006 - 2007 WRX, 2004 - 2007 STI, or 2005 - 2008 Forester XT) is compatible. If you have a 2002 - 2004 WRX, gather the additional parts and follow the cruise control module relocation instructions. The included SAE Quick Connection lines simplify the installation process. Just connect them securely, and you're on your way. Once installed, the AOS starts protecting your engine by keeping oil out of the intake and reducing condensation. As for maintenance, you can use a single Allen wrench to remove two bolts and break the unit down for cleaning when needed. Remember, this AOS doesn't work with most aftermarket strut tower bars, so avoid using them together.
