AVO avoS2X00G0QB001T Induction Aluminum Breather Oil Catch Tank Kit 02-05 Subaru WRX/STI/FXT
Big boost and big RPM's increase the amount of crank-case blow-by causing problems for the stock engine breathing system as it very quickly becomes overloaded. This can lead to oil being blown into the air-intake, increasing the possibility of detonation due to oil entering the combustion chambers. This can be solved by fitting AVO's oil/vapour separator tank kit, which removes oil mist from crankcase gas before it is returned back to the engines air-intake.
