REVIEWS & CUSTOMER MEDIA
Initial thoughts: Great quality product, nothing about this feels cheaply made, definitely worth the money. Instructions are provided and the AOS is fairly simple to install. My only grievance while installing was with the hose claps provided in the kit, they're very difficult to put on the hoses, so make sure you have a special set of pliers to make them easier to install. I had no other issues while installing this product. Product Performance: After installing this I noticed a significant reduction in both Fine Learn knock and Feedback knock frequency and severity, especially with 91 octane fuels, which I am restricted to because of where I live. I also feel like I'm not topping off oil as much anymore, however, I cannot say by how much. I definitely recommend this product for anyone that wants to keep their Subie nice and healthy.

Q: Which coolant ports go where with the new system? KRUSTI2 years ago
I’ve been watching tons of how to videos for installing an iag aos. This system looks almost identical other than the fact that now both coolant ports to the aos are located on the bottom of the unit. In the old one it seemed the top coolant port went to the reservoir and the lower coolant port went to the turbo hardline. Now that both coolant lines attach to the bottom I’m curious as to which line goes to which. Planning on picking one up for my 07 sti and installing myself any help would be greatly appreciated. Thanks
