IAG Performance

IAG Air/Oil Separator Install – Outback Wilderness Edition So I finally installed the IAG Air/Oil Separator (AOS) on my 2024 Subaru Outback Wilderness. Let me just say this — the product itself has its benefits, but the journey getting it on wasn’t exactly smooth sailing. 🔧 The Issues I Ran Into: 1️⃣ The install was much harder than advertised due to poor instructions and a poorly designed PCV adapter fitting. 2️⃣ That PCV adapter stripped apart during install, dropping metal shavings into my engine block and damaging the top four threads. 3️⃣ I had to pay $996.70 out of pocket to get the engine block flushed and the threads re-chased. IAG did send me a replacement part (same quality as the original), but unfortunately they didn’t take responsibility for the damage caused by their cheap

Dewey in sale went above and beyond helping me with what I needed for my 2008 subaru sti. He is a very good asset to the company, cant wait to receive my corsa veloce stradale rear facing manifold and the iag 76mm throttle body adaptor. (Edit) Parts came in the next morning and amazing wrap job to keep part safe and it looks amazing couldn't be happier

Great customer service! I've had my iag AOS installed for a little over a year now and realized the paint was starting to chip. I reached out to customer service and told them about the issue and they immediately sent out a new canister free of charge the next day! Kathy on the customer support team was awesome! Great communication. Thank you guys!!

They've worked on my car a few times now and I'd have to say they do amazing work. There is only two shops I trust with my car and this is one of them. They do all types of work from engines, suspension, they even have their own body shop. I'd highly recommend this shop if your car is heavily modded.

Edit: Adding a few pictures of the tear down from my original post 8 months ago. Please do your homework before going to any performance shop. Here’s my story/experience of IAG. Sorry in advance about the long winded review, but all details are relevant to the review. I’ve been tuned by IAG four separate times. The first tune was bolt ons - full turbo back exhaust, cold air intake, fuel pressure regulator, ebcs, fuel pump, injectors, and AOS. The car was a blast to drive, but had a knock issue. After reaching out to support I was told to rev the car out higher before giving it the sauce. Even after doing this the issue was still present. Therefore, I decided to gather more parts for the ideal setup I wanted. I added a bigger turbo, bigger intercooler, headers, and one step colder plugs.
