GrimmSpeed Air Oil Separator Red

MODEL # GRM078006R

$299.00


  • Q: Grimm speed AOS  Mason Herr2 years ago

    I was wondering if this AOS would be comparable to IAG's AOS. Like how does the air get separated from the oil in the blow by if there is no 'filter' to catch it?
    • 0 of 0 people found the following answer helpful

      A:  it's comparable in that they both try to do the same function. This one is much simpler and easier to install but not as effective as the IAG is at removing oil from the intake. So normally I would say this is a perfect unit for normal to semi-aggressive street driving, or a low to mid power build, where the IAG would be more idea for a big power build, or an aggressive street car, track car. Hope this helps :)

  • Q: grimmspeed AOS  Murph3 years ago

    How does the AOS stay secured in the filler tube?
  • Q: 2004 forester xt   monty48483 years ago

    With the gs aos does it replace the stock pcv valve or do I need to connect this off of the pcv valve?
  • Q: Power  JimmyAdeux6 years ago

    Is there a maximum power this AOS can hold? Example; 20psi, 340whp
    • 1 of 1 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.

  • Q: Instructions for fmic  xsaint77410608 years ago

    Are there directions for a fmic
    • 0 of 0 people found the following answer helpful

      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?  Evren8 years ago

    if you could shed some light that would be great on my order decision. Thanks
    • 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.

  • Q: fitment differences  TremendousWRX8 years ago

    Is there any fitment differences between this AOS and the AOS specified for the 2008+WRX aside from hoses and connectors? I am wondering if I can buy this one, and buy some 1/2 inch fuel hoses and connectors, and swap it between the two cars.
    • 0 of 0 people found the following answer helpful

      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?  Lovingmontyjr6002510 years ago

    I have a perrin front mount on my 2011 sti. and was thinking of ordering an aos to install as well, when I checked on a friends 08 hatch it doesn't look like it will fit below the piping? have you guys experienced any fitment issues of that nature?
    • 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.

    I've got a JDM Subie with a EJ20K motor, could this possibly work with that? (knowing it would probably require a little modification)

      A:  Yes this will work on your JDM motor. The install should remain relatively the same! Mike
