The snap ring fit fine. Ya, it took two people to get the damn thing in, but I did get it in. Glad that I never have to take it off

... I broke my set of snap ring pliers trying to get it in. I had to go bother my neighbor up the street to help get it in. After wrestling with it for twenty minutes I knew I couldn't get it on my own with broken snap ring pliers. Mine is in the perfect spot, you can't even see it. It's between the intercooler and the fog light on the drivers side. I have the FM FMIC kit so it routes the piping different then stock. But it fits right there nicely. The only way you can see it is if you look really hard at the grill from the passanger side. You can't see it from under the car very well and you can't see it from the top. I have it pointing towards the passenger side of the car, so it's really loud for everyone when I cruise by LOL.
Edit: FYI I still have the stock surge valve and the HKS SSQV hooked up
