The HKS Racing Suction Reloaded intake systems for 08-10 Subarus use a 200mm diameter high-flowing, wet, 2-layer, dual density, polyurethane filter element for superb performance and improved throttle response. The HKS Racing Suction Reloaded Subaru systems feature HKS's Reloaded air filter assembly which maintains HKS's race proven and patented Super Funnel design (think velocity stack). The Super Funnel design MAF improves air velocity over the stock setup. The Racing Suction Reloaded intake kit offers the same simple and easy filter element replacement process as other HKS intake systems; avoiding the need to wash or re-oil the intake filter.
