Easy to install.
The IAG aos is a part you should have already heard of if you have a modified Subie. I was able to install this myself within a weekend, and I feel a ton better about abusing my car now that I know there isnt carbon build up from blow-by.
An AOS is worth the peace of mind for any turbo subaru.
Absolutely horrible customer service from OTF and NOT shop jdm solely the products service. if you email them about the tunes they don't get back to you until the following week and at 11pm at night. and their response to their product not working and not being able to download tunes, "get another phone or laptop".
Very good quality pleased with the price and promt delivery
Delivered as promised. Good price
