I just installed the JDM EVO VII HKS Racing Suction kit. It's the real deal! No need for VTA Blow off valves, you can hear every breath this thing makes. It only took about 30 min to install. The directions are in Japanese. The only thing I had to figure out was to remove the original air box bracket. It's pretty tight working conditions. here's some pics:

 

Here's what's left over

 

Here's the kit installed

 

How's it working out for you power wise? Unnoticeable like some people have posted? Any loss in low end? I know they sound nice, and look very sexy, but that's not why WE mod our cars right!

 

here's where it conects to the turbo

 

I finished it just before dark and I haven't taken it out for a hard run yet. It does seem to be a little weaker on the low end. I have a master plan with a Forge BOV, 2.5 intercooler pipes, 3" turbo back and Apexi S-AFC II and boost controller. I think as a total package dialed in at the dyno it will be fine. A bigger intercooler and upgraded clutch is in my far future.

 

I think I'll be going with the Forge BOV along with the HKS intake as well. Stay away from the intercooler until you start getting serious though, the stocker is fine for now.
