HKS Racing Suction Kits are limited versions of Super Mega Flow intakes that come with polished aluminum piping and signature yellow SMF filter elements. These kit offer greater airflow and show quality looks from the less restrictive polished aluminum pipes.
Like it alot. Looks good in the engine bay. Let the MR BOV be audible thru the open filter. Straight, smooth pipe to the turbo. After tune, had a pretty noticable gain. Only real down side is the filters are pricy to replace.

I have one of these for my R34 Skyline, 100mm Inlet & 200mm Element.
HKS....you can't go wrong with them. They really suck hard, depening on the car and power it makes, you can really hear this suck very hard. Does the job well at it.
