Bucky Lasek brings his Subaru GC/STI Swap to Crawford for a No-Brainer Mod

Bucky brought his newest project to Crawford Performance: 2004 STI guts in a GC chassis. It was there to have an AOS installed, short for Air Oil Separator. The most important mod for your Subaru; hands down. Stock or built, it will protect your engine from excess blow-by.
What is an Air Oil Separator?
An AOS catches any excess oil that is forced in to the intake system, and routes it back in to the crankcase of your engine.
The system is closed loop and maintenance free, unlike a catch-can.
Reduces Oil Consumption
Reduces Carbon Buildup
Maintains Efficiency, Performance, and Reliability
Maintains Octane Levels

Although we do not offer a dedicated Air/Oil Separator kit for this kind of hybrid setup, we were able to retrofit a model meant for a 2004-2007 WRX or STI with a top mount intercooler: part number: S0714-1.
The power steering hard lines were bent out of the way to allow room, and the canister bolted right up to the strut tower.
NOTE: if you are to try this at home, use heat and never bend the same part of the line twice.
