Reinforced intercooler-to-throttle pipe for Legacy BR9/BM9 2.5 Turbo. Manufacturer price JPY 9,000 excluding tax. Vehicle-specific reinforced silicone with high oil resistance and a smoother inner surface than the factory pipe. Recreates the blow-by accumulation area with smooth curves to reduce intake resistance and provide a chamber effect. The factory pipe's thin lip near the clamp may fold inward with age, causing restriction and sometimes a whistling noise.
Install with the K2GEAR logo facing upward on the intercooler side. Manufacturer standard replacement labor JPY 4,000 excluding tax; approximately 30 minutes. Concurrent intercooler core blow-by oil cleaning: standard labor JPY 5,000 excluding tax, adding approximately 15 minutes. Periodic cleaning is recommended to reduce accumulated blow-by oil entering the cylinders.
