The IAG AOS is a billet aluminum canister engineered to remove dangerous crankcase vapors out of your engine. It is by-far the best solution on the market right now whether your car is stock or fully-built. Factory PCV systems recirculate crankcase gasses back into the intake which can not only cause oil buildup inside your intake, turbo, and intercooler, but also lower the effective octane of your fuel causing knock and potentially even damaging the your engine. When boost levels are turned up from stock, more crankcase gasses will be produced which makes the IAG AOS a MUST have for modified cars. 

  • Billet construction
  • Uses engine coolant to encourage moisture evaporation
  • No maintenance, no emptying, and won't leak
  • Includes all necessary fittings, hoses, and brackets
