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.
This sleek, high temperature silicone hose replaces the clunky plastic OEM piece. The interior features a uniform lining and incorporates a true taper design, eliminating any sudden neck-down in diameter found on lesser designs. The end result is a smooth, unrestricted path from the intake to the turbo inlet, adding power and improving engine responsiveness.
