Transitioning Hump Hoses

This is a must have for any intercooler that is connected solidly to the body, especially if the ends are two different sizes.  Engines have a rocking motion and piping must be allowed some free play to avoid damage to the intercooler end tanks, piping, brackets and hoses.  Each pipe should have a minimum of one hump hose per pipe.

Our hoses are made of 2-Ply Fiberglass Reinforced Silicone.  .110 wall thickness straight connection convoluted for flexibility or offset up to 10 degree.  Please email us for a quote on  sizes you do not see listed.


Silicone hose is NOT compatible with fuel or oil.

Orders received after 2:30PM PST are shipped out the next business day.
