Q: Power  JimmyAdeux2 years ago

• 0 of 0 people found the following answer helpful

  A:  Performance isn't dictated by a certain PSI, rather how much blow-by the motor has. If the engine is healthy and not a lot of blow-by is making it past the piston rings, then the AOS will function properly. If on the other hand a lot of blow-by is making it through, then the unit won't be able to separate the air/oil mixture quickly enough and you'll find oil getting in your car's intake tract.

  A:  If you have a FMIC, the instructions are identical except the bottom right port on the AOS will not go to the oem head breather hardline, it will go to your existing “T” for the head breathers.

Q: what is the difference between this and Perrin/Crawford based AOS systems?  Evren4 years ago

• 0 of 0 people found the following answer helpful

  A:  This system routes blow by back to the oil feed tube, it is also unbaffled and not recommended due to the location for heavy track use. The Crawford and Perrin AOS systems are coolant cooled and work very well for track applications. This is a simple AOS that doesn't break the bank and is much easier to install than the other two.

  A:  This AOS body is the same as the other model and the only differences are the hoses and connectors. You could use this AOS on a 2008+ WRX if you sourced your own fittings and hoses.

Q: fitment?  Lovingmontyjr600256 years ago

• 0 of 0 people found the following answer helpful

  A:  If the FMIC piping sits right on top of the oil cap, then this AOS may not work for your application. Most of the time you can push the piping over in order to install this AOS, but we cannot guarantee fitment with the Perrin FMIC.
