Silicone Reducing Elbow 3-3/8" to 3" 1820102C2 Kit with ClampsThis custom silicone elbow is 3 3 8" ID on one end and 3" ID on the other and is specifically designed to replace the discontinued p n 1820102C2 on 1994 1997 Ford Powerstroke engines. This is the turbo to breather housing silicone hose. Ford sells a kit to replace the original hose, but it's expensive and contains a plastic breather housing instead of the original aluminum one. With our hose there is no need to replace your breather housing. Handles
