4 Best Aos Stis - Holiday Sale
Best Choice01IAG PerformanceIAG Performance Air/Oil Separator (AOS) for Subaru Impreza WRX 06-07, STi 04-07 (Black)
Main highlights- TESTED FOR YEARS - The IAG Performance Street V3 Air / Oil separator (AOS) is an excellent investment to keep your EJ engine running well. The AOS maintains OEM PCV system functionality, but supplements its capacity. The IAG AOS design is based on years of extensive testing on standard and competition applications.
- SWIRL POT - The IAG Performance AOS' large, 1-liter, cast aluminum swirl pot canister more effectively separates oil from the PCV system upstream of PCV gasses return to the intake system. The IAG AOS' fully-heated cast aluminum housing, superior venting, and unique baffle design set it apart from the rest. The AOS is compatible with all fuel types, extends engine life, improves crankcase ventilation and is compatible with standard ECU calibrations.
- ORB PORTS - Aluminum body is powder coated in Red or Black Wrinkle Finish. The side of the AOS features 3 -8 ORB removable billet hose barbs. The EJ engine has 3 ports that vent crank pressure: one on each cylinder head, and another on the top of the block. Each engine vent port receives its own connection to the AOS. By giving each engine port its own entrance to the AOS, IAG has allowed for more effective and faster excavation of crankcase pressure.
- KEEPING OIL OUT - Keeping oil out of the engine intake tract is extremely important towards preventing premature mechanical failure and maintaining performance. Oil in the intake tract of the engine has several detrimental effects. The oil coats the internal portions of the intake, intercooler, and piping. This oil may cause premature failure of rubber or silicone hoses, which leads to failed connections.
- AOS BODY - Compact cast aluminum design has approximate 1 liter holding capacity integrated.
