Perfect

"It is what it says it is, a perfect fit set of replacement o-rings for Grimmspeed's awesome AOS. The original o-rings had begun to deteriorate after about 5 or 6 years. Before I installed Grimmspeed's AOS, I used to have to add half a quart of oil between changes, and I drive a relatively low mile Subie. Where's all that oil going? Through the intake a lowering the octane rating of the fuel. After the installing the AOS, I have never had to add oil to the engine between oil changes. The level stays pretty much the same."

fixed issue

"Gasket was cracked (inner seal) had some oil residue around the plumbing and separator. Rebuild kit fixed the problem. Do not attempt to clean off without gloves when installing new gaskets, will cut you real good while wiping off residue!"

Matt (5/5)

Just what I needed.

"I noticed that the o ring on my ao separator base was ripped so the seal between it and the filler tube was damaged. I was wondering if I could find another one at the hardware store or automotive store. I went to the grimmspeed website just to see what new products I can buy for future purchases when I came across the ao separator o ring rebuild kit. Just the thing I needed! No need to search for the right size anymore. I just needed the one o ring but for $10 I went for it. Easy to replace all o rings which took less than 10 minutes. Just don't forget to lubricate the o rings with a little bit of oil when installing."

Simply the best!

"My AOS started to leak sometime ago. This was an excellent product to refresh my AOS to like new. Easy to install. It only took 10mins. Seals were top notch quality! Well done Grimmspeed!"

Great kit

"After a while it seems the gaskets for my air oil separator have deteriorated. This product was the ticket to repairing it. It was easily to replace all the gaskets and I was back to leak free in no time."
