Frequently Asked Questions
Do I need an AOS on my Subaru WRX or STI?
An air/oil separator is one of the most recommended preventive maintenance upgrades for the Subaru EJ engine. The EJ's positive crankcase ventilation system recirculates oil vapour back into the intake — over time this coats the intercooler, intake piping, and throttle body with an oily residue that reduces intercooler efficiency and can foul the intake tract. The Crawford AOS captures that oil vapour before it enters the intake, keeping the system clean. It's particularly valuable for modified or high-boost builds and for Canadian owners who drive hard in varying conditions year-round.
Is the Crawford AOS compatible with a stock WRX or only modified cars?
The Crawford AOS is compatible with stock and modified WRX and STI builds alike. It is a bolt-on installation that does not require tuning changes. Most Subaru owners fit it during a service interval or as part of an initial build-out — it's considered a fundamentals upgrade rather than a performance part, though keeping the intake system clean does support consistent intercooler and engine performance.
