Silicone Turbo Inlet Hose

The Rev9 Silicone Turbo Inlet Hose is engineered to enhance your Subaru WRX or WRX STI's performance by increasing intake flow rates and air volume. Constructed from five layers of reinforced silicone, this inlet pipe offers exceptional rigidity and durability, ensuring a long service life. Its design features a smooth interior finish and a gradual taper from a 3-inch diameter down to the 2-1/4-inch turbo inlet. This smooth profile minimizes turbulence and allows the turbo to ingest air more efficiently, potentially increasing horsepower. The direct bolt-on design simplifies installation onto the stock turbo. The smooth inner surface, free from the corrugations found in stock inlet pipes, further contributes to increased air velocity and overall performance gains. This upgrade is available in black, red, or blue to complement your engine bay aesthetics. This performance turbo inlet pipe is compatible with Subaru WRX models from 2002-2007 (EJ20/EJ25 engines) and WRX STI models from 2004-2021 (EJ25 engines).
