HKS 08+ STi FMIC *Requires Smaller Battery 71007-AK001 & 70020-BF010*Features: We used R type core for larger size + low pressure loss for better performance than stock intercooler. The side tank has effective usage of air flow of core bumper open from the intercooler entrance to exit. We made it very short piping layout and large radius of bending to reduce the bad response caused by front mount layout. So it will have about same as the stock intercooler boost pressure spooling. Stock intercooler in the engine
Features:
- We used R type core for larger size + low pressure loss for better performance than stock intercooler.
- The side tank has effective usage of air flow of core bumper open from the intercooler entrance to exit.
- We made it very short piping layout and large radius of bending to reduce the bad response caused by front mount layout. So it will have about same as the stock intercooler boost pressure spooling.
- Stock intercooler in the engine compartment, the core tends to accumulate the heat from engine and cause knocking for the starting. By putting the intercooler in front help prevent the knocking and make it unbreakable tuning.
- Core size (600×255.6×103), Stock (170×525×65)
- You can improve performance with normal ECU but using HKS F-CON iS/V Pro for setting let you have more and better performance.

Cautions for Installation
- You need modify the bumper and size of battery to B19L size for installation.
- Can't use with the stock recirculation valve. SQV is installable. (The flange is welded into SQV pipe)
- Need separate Racing Suction Reloaded.
- You don't need ECU setting for exhaust system tuning, but if you do the performance will get better. With already boost-up vehicles, we recommend the setting with F-CON iS or V Pro for better performance.
- Approximate installation time is 5 to 6 hours

REALLY unsafe to walk around in these
Size: 2 pairs black L
They do what they are expected to do, but should only be used if you are stationary. The gel base makes for very unstable footing if walking around

These work
Size: 2 pairs black L
My husband loves these they help his very dry feet. As others have stated they are extremely difficult to walk in so have to be careful but they do work nicely.

Potential Fall Risk
Size: 2 pairs black L
While these socks do indeed help soften rough skin on your feet, there is a risk of falling while wearing them. Although they have treads on the bottom, which would indicate they’re safe to wear with nothing else, when you put moisturizer on and then wear them your foot can slip inside the sock . This causes you to lose your balance and fall, which happened to me. I’ve thrown them out.

I could be a foot model now!!!
Size: 1 pair black L
I wear work boots almost all of the time so I bought these to put on my feet with salycylic acid to moisturize and try to get rid of a stubborn corn on the ball of my foot. It helped drastically after a few nights of lounging in the house with them on.
