Product Description

The HKS Super Power Flow intake (part 70019-AF102) is engineered to maximize airflow and induction sound on early Subaru turbo models - including Impreza WRX GC8 (1998-2000), Forester SF5 (1998-2002), and Legacy B4/BE5 (1998-2001). Its iconic gold-anodized 200-100 mm Super Lip Funnel and three-layer dry polyurethane filter offer increased flow and sharper throttle response without requiring filter oil.

Installation is bolt-on and compatible with factory MAF setups and engine management - though ECU recalibration or flow calibration may be needed for tuned applications. The distinctive induction growl and quicker mid-range throttle response are hallmarks of the Super Power Flow design. Although not CARB-certified, the kit is widely used in vintage rally, road, and show builds.

Lightweight yet robust, this intake is built to perform under turbocharged duty, improve airflow, and remain simple to maintain. Backed by HKS authorized support and sporting HKS's legacy engineering, the 70019-AF102 is a reliable upgrade for early turbocharged Subaru enthusiasts.
