HKS RS BL5/BP5 EJ20Y - HKS70020-AF102

HKS RS BL5/BP5 EJ20Y  is a Racing Suction intake system designed for the 2003–2006 Subaru Legacy B4 (BL5) and Touring Wagon (BP5) with the EJ20Y engine, featuring a red, wet 2-layer urethane filter and aluminum pipe. It significantly improves airflow, reduces resistance, and boosts torque across the rev range.

Features:

• Performance Increase: Designed for improved airflow and faster acceleration, making the car feel as if the displacement is higher.
• Efficiency: Features a 2-layer wet-type polyurethane foam filter (red) for high intake efficiency without sacrificing cleaning ability.
• Design: Utilizes a "Super Lip Funnel" to maximize air suction, with a 200mm-80mm size configuration.
• Quality: Constructed with high-quality, durable almite aluminum for the piping and backplate.
• ECU & Tuning: Generally designed to function without requiring an ECU reset, although it is ideal to pair with exhaust systems for maximum performance.
• Note: Primarily for Manual Transmission (MT) models.
