The custom silicone construction of the COBB Turbo Inlet Hose rejects high engine bay temperatures and keeps the intake air closer to ambient temperature. The steel wire reinforced design eliminates the issue of hose collapse that other inlet hoses suffer under vacuum at peak demand, yet allows adequate flex between the engine and the intake. The COBB Turbo Inlet Hose is designed to be a direct replacement of the OEM piece. Steel sleeves are used to join the Turbo Inlet Hose to the stock intake and by-pass-valve. Installation is easy, requiring simple tools, no modifications and all hardware is included. Color choices include traditional COBB Blue and our new Stealth Black. The COBB Turbo Inlet Hose for the MAZDASPEED3 offers intelligent design, premium construction and high value.
