Is it a street car? You don't need an AOS.
If you think you need an AOS, ask yourself why.
If it's because you think you have excessive oil in the intake? An AOS isn't going to fix any issue you have. It's putting a bandaid on a bullet wound if your PCV system is pumping that much oil into the intake.
If you want the intake to be squeaky clean and oil free, ask yourself why you want that. I'm willing to bet you can't come up with a sufficiently good reason.
At the end of the day, it's your money. You'll spend it how you want, and you'll convince yourself enough to have made that decision.
If it were MY money, I'd spend it elsewhere without any hesitation.
The ONLY valid reason for an AOS, is on a car that is tracked and is equipped to actually be capable of having PCV problems in high-G, high duration turns. I'd put money that less than 1% of our member base fits that description.
